| 1 | A WO3 nanorod-Cr2O3 nanoparticle composite for selective gas sensing of 2-butanone显示文摘The hexagonal(h)-WO_3-Cr_2 O_3 nanocomposites with different W/Cr molar ratio of 4:1.10:1 and 40:1 were prepared by a facile two-step hydrothermal method, and its gas sensing properties were investigated under optimum working temperature. X-ray diffraction(XRD), scanning electron microscopy(SEM).transmission electron microscopy(TEM), high resolution transmission electron microscopy(HRTEM)were used to characterize the morphology, microstructure and crystallinity of the as-synthesized samples. The hexagonal W03 nanorods show a better crystallinity than Cr_2 O_3 nanoparticles. When the molar ratio of W/Cr is 10:1, the hexagonal WO_3-Cr_2 O_3 nanocomposite shows obvious selectivity toward2-butanone at 205℃ compared with other typical reducing gases, and the response value to 100 ppm 2-butanone can reach 5.6. However, there is no selectivity toward 2-butanone when the Cr/W molar ratio is1:4 and 1:40. Furthermore, hexagonal W03-Cr2 O3 nanocomposites have a short response and recovery time to 5 ppm 2-butanone, which is 10 s and 80 s, respectively. The measured results indicate that hexagonal WO_3-Cr_2 O_3 nanocomposite is a potential gas sensing material for monitoring volatile organic compounds(VOCs). | Qian Zhang He Zhang Mingkun Xu Zhurui Shen Qiang Wei | 2018 | Chinese Chemical Letters2018,29,3: | 2 |
| 2 | 2020 Roadmap on gas-involved photo-and electro-catalysis显示文摘Green reactions not only provide us chemical products without any pollution,but also offer us the viable technology to realize difficult tasks in normal conditions.Photo-,photoelectro-,and electrocatalytic reactions are indeed powerful tools to help us to embrace bright future.Especially,some gas-involved reactions are extremely useful to change our life environments from energy systems to liquid fuels and cost-effective products,such as H2 evolution(H2 production),02 evolution/reduction,CO2 reduction,N2 reduction(or N2 fixation) reactions.We can provide fuel cells clean H2 for electric vehicles from H2 evolution reaction(HER),at the same time,we also need highly efficient 02 reduction reaction(ORR) in fuel cells for improving the reaction kinetics.Moreover,we can get the clean oxidant O2 from water through O2 evolution reaction(OER),and carry out some reactions without posing any pollution to reaction systems.Furthermore,we can translate the greenhouse gas CO2 into useful liquid fuels through CO2 reduction reaction(CRR).Last but not the least,we can get ammonia from N2 reduction reaction(NRR),which can decrease energy input compared to the traditional Hubble process.These reactions,such as HER,ORR,OER,CRR and NRR could be realized through solar-,photoelectro-and electro-assisted ways.For them,the catalysts used play crucial roles in determining the efficiency and kinds of products,so we should consider the efficiency of catalysts.However,the cost,synthetic methods of catalysts should also be considered.Nowadays,significant progress has been achieved,however,many challenges still exist,reaction systems,catalysts underlying mechanisms,and so on.As extremely active fields,we should pay attention to them.Under the background,it has motivated us to contribute with a roadmap on ’GasInvolved Photo-and Electro-Catalysis’. | Yulu Yang Yang Tang Haomin Jiang Yongmei Chen Pingyu Wan Maohong Fan Rongrong Zhang Sana Ullah Lun Pan Ji-Jun Zou Mengmeng Lao Wenping Sun Chao Yang Gengfeng Zheng Qiling Peng Ting Wang Yonglan Luo Xuping Sun Alexander S.Konev Oleg V.Levin Panagiotis Lianos Zhuofeng Hu Zhurui Shen Qinglan Zhao Ying Wang Nadia Todorova Christos Trapalis Matthew V.Sheridan Haipeng Wang Ling Zhang Songmei Sun Wenzhong Wang Jianmin Ma | 2019 | Chinese Chemical Letters2019,30,12: | 1 |
| 3 | A photo-assisted electrochemical-based demonstrator for green ammonia synthesis显示文摘Bridging laboratory research and practical utilization is of crucial importance for the development of green ammonia synthetic technologies. A decentralized photo-assisted electrochemical-based demonstrator has been proposed for green ammonia synthesis from renewable electricity, air and water, where well-known defect-laden WO_(3) is used as the working electrode, and a commercially available PV panel supplies renewable electricity. In this demonstrator, defect-laden WO_(3) exhibits the optimum electrochemical NH_(3) formation rate(4.51 × 10^(-12)mol s^(-1)cm^(-2)) in 0.1 M K_(2)SO_(4)in a photovoltaic electrochemical(PV-EC) system. A system-level energy and cost analysis was conducted to investigate its economic viability and a general evaluation tool for system performance and cost estimation was proposed. This advance enables the possibility of integrating the small-scale green ammonia demonstrator into a stand-alone farm system. | Xiaolu Liu Zhurui Shen Xinyue Peng Lu Tian Ran Hao Lu Wang Yangfan Xu Yuping Liu Christos T.Maravelias Wei Li Geoffrey A.Ozin | 2022 | Journal of Energy Chemistry2022,31,5: | 1 |

| 6 | Amorphous carbon-linked TiO_(2)/carbon nanotube film composite with enhanced photocatalytic performance:The effect of interface contact and hydrophilicity显示文摘Carbon nanotube film(CNTF)can be used for photocatalysis and water treatment due to its porous structure,good stability and excellent electrical properties.In this work,TiO_(2)/amorphous carbon/carbon nanotube film(TCC)composite with uniform structure was prepared by a simple atomization spraying method.Rhodamine B(RhB)was used to test the photocatalytic activity of TCC.TCC composite exhibits good photocatalytic activity under ultraviolet light.In particular,the degradation efficiency of rhodamine B(RhB)by TCC sprayed with 9 layers of TiO_(2)(9 TCC)increased by 1.45 times than of TiO_(2) under ultraviolet light.The enhanced photocatalytic activity of TCC is attributed to the CNTF,which can broaden the light response range of TCC and improve the migration efficiency of electrons.The existence of amorphous carbon will promote these advances.Moreover,the better hydrophilic properties would enhance the catalytic performance happened on the solid-liquid interface.Finally,the photocatalytic mechanism and degradation intermediates of the TCC composite were proposed. | Zekun Xin Xiaodong Zhao Huiming Ji Tianyi Ma Hui Li Shuhui Zhong Zhurui Shen | 2021 | Chinese Chemical Letters2021,32,7: | 1 |

| 8 | Two-dimensional g-C_(3)N_(4)nanosheets-based photo-catalysts for typical sustainable processes显示文摘Graphitic carbon nitride(g-C_(3)N_(4))has been widely studied as a visible light responsive photocatalyst in recent years,due to its facile synthesis,low cost,high stability,and appropriate bandgap/band positions.In this review,we firstly introduce and compare various exfoliation approaches of bulk g-C_(3)N_(4)into ultrathin g-C_(3)N_(4)nanosheets.Then,many modification strategies of g-C_(3)N_(4)nanosheets are also reviewed,including heterojunction construction,doping,defect control,and structure design.Thereafter,the charge transfer mechanism in g-C_(3)N_(4)nanosheets based heterojunctions is present,e.g.,Z-scheme,S-scheme and other forms.Besides,the photocatalytic applications of g-C_(3)N_(4)nanosheets based photocatalysts are summarized including environmental remediation,energy generation and storage,organic synthesis,and disinfection.This review ends with a summary and some perspectives on the challenges and new directions in exploring g-C_(3)N_(4)nanosheets-based photocatalysts. | Xiaodong Zhao Qian Liu Xiaolei Li Huiming Ji Zhurui Shen | 2023 | Chinese Chemical Letters2023,34,11: | 0 |
| 9 | SYNTHESIS OF NANOPOROUS SILICA WITH INTERIOR COMPOSITE CELLS WITH SYNTHETIC BLOCK COPOLYPEPTIDE AS TEMPLATE显示文摘Nanoporous silica with unusual interior composite cells was synthesized with synthetic block copolypeptide Phe20-b-PBLG50 as template for the first time. Anilino-methyl triethoxy silane (AMTS) was used as an intermedium to interact with block co-polypeptide Phe20-b-PBLG50 through π-π interaction between the phenyl groups of block copolypeptide and those of AMTS. Meanwhile, AMTS co-condenses together with tetraethoxylsilane (TEOS) after hy-drolysis. The structure of composite vesicles due to the self-assembly of block copolypeptide in the or-ganic solvent was immobilized and transcribed by the formation of silica. The formation of nanopores could be ascribed to the secondary structure of block co-polypeptide and small molecular amine. Our results provide a new avenue to synthesize porous oxide materials with novel interior structures templated by the copolypeptide self-assembly under ambient con-ditions. | LIU Yuping ZHOU Huijing SHEN Zhurui LI Liying ZHOU Xingdi SUN Pingchuan YUAN Zhongyong CHEN Tiehong LI Baohui DING Datong | 2006 | Chinese Science Bulletin2006,51,4: | 0 |
| 10 | Highly efficient photocatalytic conversion of CO_(2) into CH_(4) over Cu single atom promoted heterojunction:The effect of uplifted d-band center显示文摘Photoreduction of CO_(2) to solar fuels has caused great interest,but suffers from low catalytic efficiency and poor selectivity.Herein,we designed a S-scheme heterojunction(Cu-TiO_(2)/WO_(3))with Cu single atom to significantly boost the photoreduction of CO_(2).Notably,the developed Cu-TiO_(2)/WO_(3) achieved the solardriven conversion of CO_(2) to CH_(4) with an evolution rate of 98.69μmol g^(−1) h^(−1),and the electron selectivity of CH_(4) reached 88.5%.The yield was much higher than those of pristine WO_(3),TiO_(2)/WO_(3) and Cu-TiO_(2) samples.Experimental and theoretical analysis suggested that the S-scheme heterojunction accelerated charge migration and inhibited the recombination of electron-hole pairs.Importantly,the charge separation effect of the heterojunction meliorated the position of the d-band.The uplifted d-band centers of Cu and Ti on Cu-TiO_(2)/WO_(3) not only improved the electron interaction between Cu single atoms and substrate-TiO_(2),accelerated the adsorption and activation of CO_(2) on the active sites of Cu single atom,but also optimized the Gibbs free energies of CH 4 formation pathway,leading to excellent selectivity toward CH_(4).This work provides new insights into the design of photocatalyst systems with high photocatalytic performance. | Hao Zhang Qian Liu Zhurui Shen | 2024 | Chinese Chemical Letters2024,35,2: | 0 |
| 11 | The role of Cs dopants for improved activation of molecular oxygen and degradation of tetracycline over carbon nitride显示文摘Molecular oxygen(O_(2))is activated to reactive oxygen species(ROS)by transferring energy and carriers in the photocatalytic process,which plays an important role in environmental remediation.Herein,Cs-doped carbon nitride(CN-xCs,x=0.2,0.8,1)was prepared by CsCl directly inducing the structural reconstruction of carbon nitride(CN),which had obvious molecular oxygen activation ability to promote tetracycline(TC)degradation.Besides,we explored the influence of Cs doping concentration.As a consequence,the doping concentration of Cs was an important factor affecting the activation of O_(2),which could cause changes in the physical and chemical structure of CN,make O enter the CN structure,form N vacancy defects and cyano groups.In addition,a proper amount of Cs doping could reduce the band gap value,increase the light absorption range,have better charge separation and transfer performance,which could remarkably promote the activation of O_(2).Benefiting from these advantages,CN-0.8Cs could generate a higher concentration of superoxide radicals(•O_(2)^(−),179.30µmol/L),which was much higher than CN(6.22µmol/L).Therefore,it exhibited excellent TC degradation photocatalytic performance,and the rate constant k of TC degradation was 0.020 min^(−1),which was 6.7 times the degradation rate of CN(k=0.0030 min^(−1)).Furthermore,the possible degradation pathways of TC were proposed based on the results of HPLC-MS. | Qian Liu Hui Li Hao Zhang Zhurui Shen Huiming Ji | 2022 | Chinese Chemical Letters2022,33,11: | 0 |
