| 1 | Cenozoic uplift of the Tibetan Plateau:Evidence from the tectonic-sedimentary evolution of the western Qaidam Basin显示文摘Geologists agree that the collision of the Indian and Asian plates caused uplift of the Tibet Plateau.However,controversy still exists regarding the modes and mechanisms of the Tibetan Plateau uplift.Geology has recorded this uplift well in the Qaidam Basin.This paper analyzes the tectonic and sedimentary evolution of the western Qaidam Basin using sub-surface seismic and drill data. The Cenozoic intensity and history of deformation in the Qaidam Basin have been reconstructed based on the tectonic developments,faults growth index,sedimentary facies variations,and the migration of the depositional depressions.The changes in the sedimentary facies show that lakes in the western Qaidam Basin had gone from inflow to still water deposition to withdrawal.Tectonic movements controlled deposition in various depressions,and the depressions gradually shifted southeastward.In addition,the morphology of the surface structures in the western Qaidam Basin shows that the Cenozoic tectonic movements controlled the evolution of the Basin and divided it into(a) the southern fault terrace zone, (b) a central Yingxiongling orogenic belt,and(c) the northern fold-thrust belt;divided by the XI fault (Youshi fault) and Youbei fault,respectively.The field data indicate that the western Qaidam Basin formed in a Cenozoic compressive tectonic environment caused by the India—Asia plate collision. Further,the Basin experienced two phases of intensive tectonic deformation.The first phase occurred during the Middle Eocene—Early Miocene(Xia Ganchaigou Fm.and Shang Ganchaigou Fm.,43.8—22 Ma),and peaked in the Early Oligocene(Upper Xia Ganchaigou Fm.,31.5 Ma).The second phase occurred between the Middle Miocene and the Present(Shang Youshashan Fm.and Qigequan Fm., 14.9—0 Ma),and was stronger than the first phase.The tectonic—sedimentary evolution and the orientation of surface structures in the western Qaidam Basin resulted from the Tibetan Plateau uplift,and recorded the periodic northward growth of the Plateau.Recognizing this early tectonic—sedimentary evolution supports the previous conclusion that northern Tibet responded to the collision between India and Asia shortly after its initiation.However,the current results reveal that northern Tibet also experienced another phase of uplift during the late Neogene.The effects of these two stages of tectonic activity combined to produce the current Tibetan Plateau. | Yadong Wang Jianjing Zheng Weilin Zhang Shiyuan Li Xingwang Liu Xin Yang Yuhu Liu | 2012 | Geoscience Frontiers2012，3，2： | 23 |
| 2 | Gas Hydrates in the Qilian Mountain Permafrost, Qinghai, Northwest China显示文摘Qilian Mountain permafrost, with area about 10×104 km2, locates in the north of Qinghai-Tibet plateau. It equips with perfect conditions and has great prospecting potential for gas hydrate. The Scientific Drilling Project of Gas Hydrate in Qilian Mountain permafrost, which locates in Juhugeng of Muri Coalfield, Tianjun County, Qinghai Province, has been implemented by China Geological Survey in 2008–2009. Four scientific drilling wells have been completed with a total footage of 2059.13 m. Samples of gas hydrate are collected separately from holes DK-1, DK-2 and DK-3. Gas hydrate is hosted under permafrost zone in the 133–396 m interval. The sample is white crystal and easily burning. Anomaly low temperature has been identified by the infrared camera. The gas hydrate-bearing cores strongly bubble in the water. Gas-bubble and water-drop are emitted from the hydrate-bearing cores and then characteristic of honeycombed structure is left. The typical spectrum curve of gas hydrate is detected using Raman spectrometry. Furthermore, the logging profile also indicates high electrical resistivity and sonic velocity. Gas hydrate in Qilian Mountain is characterized by a thinner permafrost zone, shallower buried depth, more complex gas component and coal-bed methane origin etc. | ZHU Youhai ZHANG Yongqin WEN Huaijun LU Zhenquan JIA Zhiyao LI Yonghong LI Qinghai LIU Changling WANG Pingkang GUO Xingwang | 2010 | Acta Geologica Sinica(English Edition)2010，84，1： | 19 |
| 3 | A novel advanced oxidation process——wet electrocatalytic oxidation for high concentrated organic wastewater treatment显示文摘A novel advanced oxidation process——wet electrocatalytic oxidation (WEO) was studied with p-nitrophenol as model pollutant and β-PbO2 electrode as the anode. Compared with the effect of the individual wet air oxidation (WAO) and electrochemical oxidation (EO), the effect of WEO showed syn- ergistic effect on COD removal under the conditions of temperature 160℃, C=1000 mg·L-1, PN2=0.50 MPa, PO2=0.9 MPa, current density = 3 mA·cm-2, Na2SO4 3 g·L-1. And the synergistic factor got the best value of 0.98 within 120 min after 180 min treatment. The synergistic factor was studied after 120 min treatment at 100℃, 120℃, 140℃ and 160℃, and the effect of 120℃ was the best with the value of 1.26. Possible mechanism for the synergistic effect was discussed based on the analysis of free-radical generation and intermediates detected by HPLC and GC/MS. | DAI QiZhou ZHOU MingHua LEI LeCheng ZHANG XingWang | 2007 | Chinese Science Bulletin2007，52，12： | 11 |
| 4 | Comprehensive analysis of NAC transcription factors and their expression during fruit spine development in cucumber (Cucumis sativus L.)显示文摘The cucumber(Cucumis sativus L.)is an important vegetable crop worldwide,and fruit trichomes or spines are an important trait for external fruit quality.The mechanisms underlying spine formation are not well understood,but the plant-specific NAC family of transcription factors may play important roles in fruit spine initiation and development.In this study,we conducted a genome-wide survey and identified 91 NAC gene homologs in the cucumber genome.Clustering analysis classified these genes into six subfamilies;each contained a varying number of NAC family members with a similar intron–exon structure and conserved motifs.Quantitative real-time PCR analysis revealed tissue-specific expression patterns of these genes,including 10 and 12 that exhibited preferential expression in the stem and fruit,respectively.Thirteen of the 91 NAC genes showed higher expression in the wild-type plant than in its near-isogenic trichome mutant,suggesting their important roles in fruit spine development.Exogenous application of four plant hormones promoted spine formation and increased spine density on the cucumber fruits;several NAC genes showed differential expression over time in response to phytohormone treatments on cucumber fruit,implying their essential roles in fruit-trichome development.Among the NAC genes identified,12 were found to be targets of 13 known cucumber micro-RNAs.Collectively,these findings provide a useful resource for further analysis of the interactions between NAC genes and genes underlying trichome organogenesis and development during fruit spine development in cucumber. | Xingwang Liu Ting wang Ezra Bartholomew Kezia Black Mingming Dong Yaqi Zhang Sen Yang Yanling Cai Shudan Xue Yiqun Weng Huazhong Ren | 2018 | Horticulture Research2018，5，1： | 10 |
| 5 | Gas chromatography-mass spectrometry analysis of essential oils from five parts of Chaihu(Radix Bupleuri Chinensis)显示文摘OBJECTIVE: To analyze the essential oils from flowers, leaves, stems, roots, and fruits of Chaihu(Radix Bupleuri Chinensis).METHODS: We extracted essential oils from different parts of Chaihu(Radix Bupleuri Chinensis) using a steam distillation method. The essential oils were analyzed by gas chromatography-mass spectrometry(GC-MS). Data were collected in full scan mode(m/z 60-600). Volatile components were identified based on their retention indices and by comparing their mass spectra with those in the National Institute of Standards and Technology 2005 database assisted by tandem mass spectrometry information. The relative content of each constituent wasdetermined by area normalization.RESULTS: We identified 111 components, of which12 were common to all 5 parts, 30 were found only in roots, 14 were found only in flowers, 6 were found only in leaves, 4 were found only in stems,and 17 were found only in fruits.CONCLUSION: Our results show that the stems,flowers, leaves, and fruits of Chaihu(Radix Bupleuri Chinensis)contain a high concentration of essential oils, and that the exact composition of the essential oils differs among the plant parts. To develop new medicines and make full use of the Chaihu(Radix Bupleuri Chinensis)resource, it is important to characterize the essential oils from different parts of the plant. In future research, it will be important to determine the pharmacological effects of the various components and the essential oil mixtures. | Jie Meng Xingfu Chen Wenyu Yang Jiuhua Song Yu Zhang Zhifei Li Xingwang Yang Zhanguo Yang | 2014 | Journal of Traditional Chinese Medicine2014，34，6： | 9 |
| 6 | Fabrication of visible-light responsive S-F-codoped TiO_2 nanotubes显示文摘Fabrication and S-F-codoping of TiO2 nanotubes were carried out by a one-step electrochemical ano-dization process to extend the photoresponse of TiO2 to the visible-light region. The prepared samples were annealed in air and detected by SEM,XRD,XPS and UV-vis DRS spectrophotometer. The results showed that the average tube diameter of the nanotubes was 150 nm and the average tube length was 400 nm. The doped TiO2 nanotubes exhibited strong absorption in visible-light region. Photoelectro-catalytic degradation efficiency of 4-CP over S-F-codoped TiO2 nanotubes was 39.7% higher than that of only-F-doped sample. Moreover,sulfur and fluorine codoped into substitutional sites of TiO2 had been proven to be indispensable for strong response and high photocatalytic activity under visible light,as assessed by XPS. | CHEN XiuQin SU YaLing ZHANG XingWang LEI LeCheng | 2008 | Chinese Science Bulletin2008，53，13： | 7 |
| 7 | Enhanced Vitamin C Production Mediated by an ABA-Induced PTP-like Nucleotidase Improves Plant Drought Tolerance in Arabidopsis and Maize显示文摘Abscisic acid(ABA)is a key phytohormone that mediates environmental stress responses.Vitamin C,or L-ascorbic acid(AsA),is the most abundant antioxidant protecting against stress damage in plants.How the ABA and AsA signaling pathways interact in stress responses remains elusive.In this study,we characterized the role of a previously unidentified gene,PTPN(PTP-like Nucleotidase)in plant drought tolerance.In Arabidopsis,(AtPTPN was expressed in multiple tissues and upregulated by ABA and drought treatments.Loss-of-function mutants oiAtPTPN were hyposensitive to ABA but hypersensitive to drought stresses,whereas plants with enhanced expression AtPTPN showed opposite phenotypes to.Overexpression of maize PTPN(ZmPTPN)promoted,while knockdown oiZmPTPN inhibited plant drought tolerance,indicating conserved and positive roles of PTPN in plant drought tolerance.We found that both AtPTPN and ZmPTPN release Pi by hydrolyzing GDP/GMP/dGMP/IMP/dIMP,and that AtPTPN positively regulated AsA production via endogenous Pi content control.Consistently,overexpression of VTC2,the rate-limiting synthetic enzyme in AsA biosynthesis,promoted AsA production and plant drought tolerance,and these effects were largely dependent on AtPTPN activity.Furthermore,we demonstrated that the heat shock transcription factor HSFA6a directly binds the AtPTPN promoter and activates AtPTPN expression.Genetic analyses showed that AtPTPN is required for HSFA6a to regulate ABA and drought responses.Taken together,our data indicate that PTPN-mediated crosstalk between the ABA signaling and AsA biosynthesis pathways positively controls plant drought tolerance. | Hui Zhang Yanli Xiang Neng He Xiangguo Liu Hongbo Liu Liping Fang Fei Zhang Xiaopeng Sun Delin Zhang Xingwang Li William Terzaghi Jianbing Yan Mingqiu Dai | 2020 | Molecular Plant2020，13，5： | 7 |
| 8 | Synergistic improvement of perovskite film quality for efficient solar cells via multiple chloride salt additives显示文摘Perovskite crystal film quality is critical for obtaining efficient perovskite solar cells. Anti-solvent processing was used for fast crystallization of perovskite precursor film, which can form dense perovskite film.However, the crystals from this method are usually small due to the fast crystal growth process, which could lead to grain boundary recombination. Here, element chloride is introduced to enhance the perovskite layer crystallinity via slowing down the perovskite crystallization process by simultaneous introduction of methylammounium chloride(MACl) and cesium chloride(CsCl) into precursor solution.As a result, we achieve high quality of pin-hole free perovskite film with large crystal size. A power conversion efficiency of 21.55% with free of hysteresis of the device is obtained, which is among the highest efficiency of planar structure perovskite solar cells. | Pengyang Wang Qi Jiang Yang Zhao Yong Chen Zema Chu Xingwang Zhang Yuqin Zhou Jingbi You | 2018 | Science Bulletin2018，63，11： | 6 |
| 9 | Non-noble metal single-atom catalysts prepared by wet chemical method and their applications in electrochemical water splitting显示文摘Water splitting by electrolysis is an appealing pathway for sustainable hydrogen production. The practical performance of water splitting is highly dependent on the efficiency of electrocatalysts, which can promote the anodic oxygen evolution reaction(OER) or cathodic hydrogen evolution reaction(HER). Downsizing the metal nanostructures to atomic level to construct single-atom catalysts(SACs) has attracted enormous attention due to its distinct advantages in maximizing the efficiency of metal atom utilization and enhancing activity over corresponding metal nanoparticles. Research on SACs towards electrochemical water splitting application is an emerging field and intensive investigations have been focused on their rational syntheses and applications in HER/OER. In this review, we focus on the wet chemical method developed to prepare non-noble metal based SACs with an emphasis on the synthetic strategies and structure-activity relationship between single metal atoms and catalytic activity. Finally, the challenges and future opportunities for application of single-atom catalysts in water splitting are briefly addressed. | Wei Liu Hongxiu Zhang Chuanming Li Xin Wang Jingquan Liu Xingwang Zhang | 2020 | Journal of Energy Chemistry2020，29，8： | 6 |
| 10 | Application of in-plasma catalysis and post-plasma catalysis for methane partial oxidation to methanol over a Fe_2O_3-CuO/γ-Al_2O_3 catalyst显示文摘Methane partial oxidation to methanol (MPOM) using dielectric barrier discharge over a Fe2O3-CuO/γ-Al2O3 catalyst was performed.The multicomponent catalyst was combined with plasma in two different configurations,i.e.,in-plasma catalysis (IPC) and post-plasma catalysis (PPC).It was found that the catalytic performance of the catalysts for MPOM was strongly dependent on the hybrid configuration.A better synergistic performance of plasma and catalysis was achieved in the IPC configuration,but the catalysts packed in the discharge zone showed lower stability than those connected to the discharge zone in sequence.Active species,such as ozone,atomic oxygen and methyl radicals,were produced from the plasma-catalysis process,and made a major contribution to methanol synthesis.These active species were identified by the means of in situ optical emission spectra,ozone measurement and FT-IR spectra.It was confirmed that the amount of active species in the IPC system was greater than that in the PPC system.The results of TG,XRD,and N2 adsorption-desorption revealed that carbon deposition on the spent catalyst surface was responsible for the catalyst deactivation in the IPC configuration. | Lin Chen Xingwang Zhang Liang Huang Lecheng Lei | 2010 | Journal of Natural Gas Chemistry2010，19，6： | 5 |
| 11 | Identification of the starting reaction position in the hydrogenation of (N-ethyl)carbazole over Raney-Ni显示文摘Hydrogenation of carbazole and N-ethylcarbazole over Raney-Ni catalyst were realized in the temperature range of 393-503 K. 4[H] adduct dominated the hydrogenation products and the formation of 2[H] adduct was the rate-limiting step during the period, in which the conversion of carbazole was less than 40%. The hydrogenation process followed pseudo-first-order kinetics and the hydrogenation activation energies of carbazole and N-ethylcarbazole were 90 k J/mol and 115 k J/mol, respectively. The reaction starting position as well as the pathway of the hydrogenation of(N-ethyl)carbazole were investigated by comparing the kinetic characteristics of hydrogen uptake of carbazole and Nethylcarbazole. The results showed that the reaction was a stepwise hydrogenation process and the first H2 was added to the C1 = C10 double bond in the hydrogenation. | Feifei Sun Yue An Lecheng Lei Fuying Wu Jingke Zhu Xingwang Zhang | 2015 | Journal of Energy Chemistry2015，24，2： | 4 |
| 12 | Physical characterization of meloxicam-β-cyclodextrin inclusion complex pellets prepared by a fluid-bed coating method显示文摘Meloxicam-β-cyclodextrin (ME-β-CD) inclusion complex was prepared by a fluid-bed coating technique upon solvent removal and simultaneous depositing onto the surface of nonpareil pellets and using PVP K30 as a binding agent to facilitate good coating. The resultant pellets were spherical and intact in shape with good flowability and friability. SEM analysis showed that the pellets were smooth and had a tightly coated inclusion complex layer. In vitro dissolution of the inclusion complex pellets in pH 7.4 phosphate buffer was dramatically enhanced at an ME/CD ratio of 1/1. DSC and powder X-ray diffractometry proved the absence of crystallinity in the ME/CD inclusion complexes. Moreover, Fourier transform-infrared spectrometry together with Raman spectrometry indicated that the thiazole ring of ME was possibly included in the cavity of β-CD. | Yi Lu Xingwang Zhang Jie Lai Zongning Yin Wei Wu | 2009 | Particuology2009，7，1： | 4 |
| 13 | Polycyclic aromatic hydrocarbons in the centralized wastewater treatment plant of a chemical industry zone:Removal,mass balance and source analysis显示文摘Increased attention has been given to the fate of pollutants such as polycyclic aromatic hydrocarbons (PAHs) introduced to the wastewater treatment plants.Dissolved and adsorbed PAHs were detected in the centralized wastewater treatment plant of a chemical industry zone in Zhejiang Province,China.The most abundant PAHs were the low molecular weight PAHs (e.g.,Acy,Ace,Flu and Phe),accounting for more than 80% of the total 16 PAHs in each treatment stage.Phase partitioning suggested that the removal of PAHs in every treatment stage was influenced greater by the sorption of particles or microorganisms.The removal efficiencies of individual PAHs ranged between 4% and 87% in the primary sedimentation stage,between 1% and 42% in anaerobic hydrolysis stage,between <1% and 70% in aerobic bio-process stage,between 1.5% and 80% in high-density clarifier stage,and between 44% and 97% in the whole treatment process.Mass balance calculations in primary stage showed significant losses for low molecular weight PAHs and relatively good agreements for high molecular weight PAHs as well as in anaerobic hydrolysis,high-density clarifier stage and sludge stream for most PAHs.Great gains of 60%-150% were obtained for high molecular weight PAHs in aerobic bio-process stage due to biosorption and bioaccumulation.Our investigations found that PAHs entering the wastewater treatment plant (WWTP) could be derived from the dyeing chemical processes as the byproducts,and the contribution supported by the largest dyeing chemical group was up to 48%. | YAO Min ZHANG XingWang LEI LeCheng | 2012 | Science China Chemistry2012，55，3： | 4 |
| 14 | Quantifying the effectiveness of SiO_2/Au light trapping nanoshells for thin film poly-Si solar cells显示文摘In order to enhance light absorption of thin film poly-crystalline silicon(TF poly-Si)solar cells over a broad spectral range, and quantify the effectiveness of nanoshell light trapping structure over the full solar spectrum in theory,the effective photon trapping flux(EPTF)and effective photon trapping efficiency(EPTE)were firstly proposed by considering both the external quantum efficiency of TF poly-Si solar cell and scattering properties of light trapping structures.The EPTF,EPTE and scattering spectrum exhibit different behaviors depending on the geometric size and density of nanoshells that form the light trapping layer.With an optimum size and density of SiO2/Au nanoshell light trapping layer,the EPTE could reach up to 40%due to the enhancement of light trapping over a broad spectral range,especially from 500 to 800 nm. | BAI YiMing 1 ,WANG Jun 2 ,CHEN NuoFu 1,3 ,YAO JianXi 1 ,YIN ZhiGang 3 ,ZHANG Han 3 , ZHANG XingWang 3 ,HUANG TianMao 3 ,WANG YanShuo 3 &YANG XiaoLi 3 1School of Renewable Energy Engineering,North China Electric Power University,Beijing 102206,China 2 National Engineering Research Center for Optoelectronic Devices,Institute of Semiconductors, Chinese Academy of Sciences,PO Box 912,Beijing 100083,China 3 Key Laboratory of Semiconductor Materials Science,Institute of Semiconductors, Chinese Academy of Sciences,PO Box 912,Beijing 100083,China | 2010 | Science China(Technological Sciences)2010，53，8： | 4 |
| 15 | Materials Experiment on Tiangong-2 Space Laboratory显示文摘During the China's Tiangong-2(TG-2) flight mission, the experiments of 18 kinds of material samples were conducted in space by using a Multiple Materials Processing Furnace(MMPF) mounted in the orbital module of the TG-2 space laboratory. After the experiments of 12 kinds of samples of the first and second batches were completed successfully, astronauts packed and brought them back to the ground by ShenzhouII spacecraft. By studying processing and formation on semiconductor and optoelectronics materials, metal alloys and metastable materials, functional single-crystal, micro-and nano-composite materials encapsulated in sample ampoules both in space and on Earth, we expect to explore some physical and chemical processes and mechanism of the materials formation that are normally obscured and therefore are difficult to study quantitatively on the ground due to the gravity-induced convection, to obtain the processing and synthesis technology for preparing high quality materials, and lead to the improvement and development of materials processing techniques on Earth, and also develop the experiment device and comprehensive ability for materials experiment in microgravity environment. This report briefly introduces the main points of each research work and preliminary comparative analysis results of 12 samples carried out by scientists undertaking research task. | LI Xiangyang LU Ye MENG Xiangjian WANG Jianlu WANG Reng CHEN Lidong HUA Zile LI Xiaoya SHI Jianlin LIU Jinfeng XU Guisheng WEI Bingbo XIE Wenjun YIN Zhigang ZHANG Xingwang JIANG Hongxiang LI Hong LUO Xinghong ZHANG Haifeng ZHAO Jiuzhou WANG Binbin PAN Mingxiang | 2018 | 空间科学学报2018，38，5： | 4 |
| 16 | Design of Fault Detection Observer Based on Hyper Basis Function显示文摘In this paper, we propose the Hyper Basis Function(HBF) neural network on the basis of Radial Basis Function(RBF) neural network. Compared with RBF, HBF neural networks have a more generalized ability with different activation functions. A decision tree algorithm is used to determine the network center. Subsequently, we design an adaptive observer based on HBF neural networks and propose a fault detection and diagnosis method based on the observer for the nonlinear modeling ability of the neural network. Finally, we apply this method to nonlinear systems. The sensitivity and stability of the observer for the failure of the nonlinear systems are proved by simulation, which is beneficial for real-time online fault detection and diagnosis. | Xin Wen Xingwang Zhang Yaping Zhu | 2015 | Tsinghua Science and Technology2015，20，2： | 4 |

| 18 | Modification of TiO_2 nanotubes arrays by CdS and their photoelectrocatalytic hydrogen generation properties显示文摘In order to realize hydrogen generation under visible light, novel CdS/TiO_2 nanotubes arrays are de- veloped by electrochemical anodization of Ti in 0.15 mol/L NH_4F + 0.08mol/L H_2C_2O_4 electrolyte. The diameter of the nanotube is 80―100nm and the length is approximately 550 nm. The CdS nano-particles are deposited on the TiO_2 nanotubes arrays by chemical bath deposition (CBD) in the ammonia-thiourea system. A 300W Xe lamp is used as the light source, CdS/TiO_2 nanotube arrays are used as the photoanode with the application of 1.0V bath voltage, and 0.1 mol/L Na_2S + 0.04 mol/L Na_2SO_3 solution is used as the electrolyte, then the rate of photoelectrocatalytic hydrogen generation is 245.4 μL/(h·cm^2). This opens new perspectives for photoelectrocatalytic hydrogen generation by using CdS/TiO_2 nanotubes arrays. | ZHANG JianLing ZHANG XingWang LEI LeCheng | 2008 | Chinese Science Bulletin2008，53，12： | 3 |
| 19 | Preparation of TiO_2/ITO film electrode by AP-MOCVD for photoelectrocatalytic application显示文摘Titanium dioxide (TiO2 ) thin films were grown onto Indium tin oxide (ITO) glass under atmospheric pressure by chemical vapor deposition (AP-MOCVD) using titanium tetraisopropoxide astitanium precursor. The as-prepared TiO2 /ITO films were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and photoelectrochemical measurements. Their photocatalytic (PC) and photoelectrocatalytic (PEC) activities were evaluated based on the results of methyl orange dye (MO) degradation experiments in aqueous solution. The difference between the front side (EE, electrolyte/electrode interface) and the back side (SE, substrate/electrode interface) illumination was evaluated in both photocurrent and MO degradation experiments. The effect of the film thickness on degradation rate by PEC under the two illumination directions was also studied. Stability of TiO2 /ITO film electrode was investigated in repetitive degradation experiments. Overall, the TiO2 /ITO film with thickness ranging from 321 to1440 nm deposited by MOCVD method is an effective photoelectrode for MO degradation under SE illumination in PEC reaction system. | HAN Song ZHANG XingWang YU QingNi LEI LeCheng | 2012 | Science China Chemistry2012，55，11： | 3 |
| 20 | Nickel oxide for inverted structure perovskite solar cells显示文摘The emergence of inverted perovskite solar cells(PSCs) has attached great attention derived from the potential in improving stability. Charge transporting layer, especially hole transporting layer is crucial for efficient inverted PSCs. Organic materials were used as hole transporting layer previously. Recently, more and more inorganic hole transporting materials have been deployed for further improving the device stability. Nickel oxide(NiOx) as p-type metal oxide, owning high charge mobility and intrinsic stability,has been widely adopted in inverted PSCs. High performance over 20% efficiency has been achieved on NiOx base inverted PSCs. Herein, we have summarized recent progresses and strategies on the NiOx based PSCs, including the synthesis or deposition methods of NiOx, doping and surface modification of NiOx for efficient and stable PSCs. Finally, we will discuss current challenges of utilizing NiOx HTLs in PSCs and attempt to give probable solutions to make further development in efficient as well as stable NiOx based PSCs. | Fei Ma Yang Zhao Jinhua Li Xingwang Zhang Haoshuang Gu Jingbi You | 2021 | Journal of Energy Chemistry2021，30，1： | 3 |
