1Layered double hydroxide-based photocatalytic materials toward renewable solar fuels production显示文摘Photocatalysis is an ideal and promising green technology to drive numerous chemical reactions for valued chemicals production under very mild conditions,thereby providing solutions to global energy and environment issues related to burning fossil fuels.Over the past decade,layered double hydroxides(LDHs),as the members in two-dimensional materials family,have attracted much attention due to their many advantages in photocatalysis,such as facile synthesis,low cost and powerful tunability of composition.In this review,we provide a synthetic overview of recent research advances of LDH-based photocatalysts,with the main discussion of the design strategies to improve their photocatalytic performance,including component control,defect engineering,hybridization,and topological transformation.Structure-performance correlations and tailor-made material synthesis strategies are elaborated to discuss how to realize high-performance LDH-based photocatalysts for three important reactions(i.e.,water splitting,CO_(2)conversion,and N2 reduction)to generate desirable solar fuels.Further,the remaining challenges and future perspectives of LDH-based photocatalysts are summed up,aiming to inspire brand new solutions for pushing forward the development of LDH-based photocatalysis.Xuanang Bian Shuai Zhang Yunxuan Zhao Run Shi Tierui Zhang 2021InfoMat2021,3,7:5
2Degradation of poly(butylene adipate-co-terephthalate) by Stenotrophomonas sp. YCJ1 isolated from farmland soil显示文摘In recent years, poly(butylene adipate-co-terephthalate)(PBAT) has been widely used. However, PBAT-degrading bacteria have rarely been reported. PBAT-degrading bacteria were isolated from farmland soil and identified. The effects of growth factors on the degradation of PBAT and the lipase activity of PBAT-degrading bacteria were assessed. The degradation mechanism was analyzed using scanning electron microscopy, attenuated total reflection Fourier transform infrared spectroscopy, proton nuclear magnetic resonance, Xray diffraction, and liquid chromatography-mass spectrometry. The results showed that Stenotrophomonas sp. YCJ1 had a significant degrading effect on PBAT. Under certain conditions, the strain could secrete 10.53 U/m L of lipase activity and degrade 10.14 wt.% of PBAT films. The strain secreted lipase to catalyze the degradation of the ester bonds in PBAT, resulting in the production of degradation products such as terephthalic acid, 1,4-butanediol, and adipic acid. Furthermore, the degradation products could participate in the metabolism of YCJ1 as carbon sources to facilitate complete degradation of PBAT, indicating that the strain has potential value for the bioremediation of PBAT in the environment.Hao Jia Min Zhang Yunxuan Weng Yao Zhao Chengtao Li Aqsa Kanwal 2021Journal of Environmental Sciences2021,33,5:4

4Ultrafine monolayer Co-containing layered double hydroxide nanosheets for water oxidation显示文摘For many two-dimensional(2D)materials,low coordination edges and corner sites offer greatly enhanced catalytic performance compared to basal sites,motivating the search for new synthetic approaches towards ultrathin and ultrafine 2D nanomaterials with high specific surface areas.To date,the synthesis of catalysts that are both ultrathin(monolayer)and ultrafine(lateral size<10nm)has proven extremely challenging.Herein,using a facile ultrasonic exfoliation procedure,we describe the successful synthesis of ultrafine ZnCo-LDH nanosheets(denoted as ZnCo-UF)with a size^3.5 nm and thickness^0.5 nm.The single layer ZnCo-UF nanosheets possess an abundance of oxygen vacancies(Vo)and unsaturated coordination s让es,thereby affording outstanding electrocatalytic water oxidation performance.DFT calculations confirmed that Vo on the surface of ZnCo-UF enhanced H20 adsorption via increasing the electropositivity of the nanosheets.Xiaodan Jia Xin Zhang Jiaqing Zhao Yufei Zhao Yunxuan Zhao Geoffrey I.N.Waterhouse Run Shi Li-Zhu Wu Chen-Ho Tung Tierui Zhang 2019Journal of Energy Chemistry2019,28,7:3

7The Study of Nerve Conduit with Biocompatibility and Electrical Stimulation Effect显示文摘Conductive polymers show great promise because of their electrical property based on bioelectricity in vivo. In order to search electro-activity materials which insure abduction of tissue, we synthesized conductive nerve conduits with poly-dl-lactic-acid(PDLLA) and tetra-aniline(TA). Preparation technology of TA was optimized, and the properties of the conduit were studied. RSC96 cell were used to investigate the toxicity and electrical stimulation effect. SD rats were used to assess biocompatibility in vivo. The results showed that the reaction ratio of 1:1, the reaction time of 2 h and the HCl concentration of 2 mol/L were the optimum conditions for synthesis of TA. The influence of TA content on the mechanical properties, hydrophilicity, conductivity and microstructure of the nerve conduit was evaluated. Cell and histocompatibility study showed PDLLA/TA possessed good biocompatibility. These results showed it had application values in tissue projects.郭兴蕾 刘刚 HE Qundi 徐海星 YU Yunxuan KE Changsheng MING Xiaofei ZHAO Meng WANG Xiaobin HUANG Zhijun 许沛虎 2018Journal of Wuhan University of Technology(Materials Science)2018,33,6:1
8Progress and Prospect of Photothermal Catalysis显示文摘Recently,solar-driven synthesis due to its energy-saving and environmentally friendly advantages has attracted more and more attention,whereas the low solar-to-chemical conversion efficiency significantly hindered its development.New effective options that fully utilize full-band sunlight are urgently needed.Novel photothermal catalysis combined with the advantages of photocatalysis and thermalcatalysis can improve the utilization efficiency of solar energy and lower the reaction temperature,thus becoming a promising technology.This review divides photothermal catalysis into photo-assisted thermalcatalysis,thermal-assisted photocatalysis,and photothermal synergistic catalysis.Furthermore,the catalytic mechanical understanding of how photothermal affects the catalytic property of different applications(e.g.,water splitting,CO_(2)/N_(2) reduction,and environmental treatment)was also summed up and discussed in detail.The discussion ends with unsolved challenges in photothermal catalysis,particularly emphasizing the effect of temperature or sunlight on catalytic performance.DU Shihao BIAN Xuanang ZHAO Yunxuan SHI Run ZHANG Tierui 2022Chemical Research in Chinese Universities2022,38,3:1

10Analysis of key parameters sensitivity and calibration accuracy of signal timing algorithm显示文摘A theoretical sensitivity analysis of total lost timeand saturated flow rate is conducted based on the methodproposed in the Highway Capacity Manual (HCM). Inaddition, the accuracy of the timing calculation algorithmsuggested in the HCM is verified using field data from threeintersections. It is demonstrated that there is a positivecorrelation between the estimation error rates of the signalcycle length and the phase lost time. Also, the estimated valueof saturated flow rate must meet the specific requirementsunder different saturated conditions to guarantee the accuracyof the signal cycle length. However, through analysis of fielddata collected on the discharge headway in three intersections,it is also found that, if the 4th vehicle is set as the initial spotfor the stable discharge headway, as is recommended in theHCM, the error of the phase lost time will be over 40% whenthe line length is over 10 vehicles. Moreover, the calculationerror for signal cycle length is not guaranteed to fall within the15% range when the length of line is over 15 vehicles. It issuggested that, to improve the applicability of the HCMmethod, a more accurate description of the distributedregularity of the discharge headway is necessary whencalibrating key parameters.Zhao Yi Zhong Ning Lu Jian Li Yunxuan 2017Journal of Southeast University(English Edition)2017,33,3:0
11Spatiotemporal dynamics of population density in China using nighttime light and geographic weighted regression method显示文摘The distribution and dynamic changes of regional or national population data with long time series are very important for regional planning,resource allocation,government decision-making,disaster assessment,ecological protection,and other sustainability research.However,the existing population datasets such as LandScan and WorldPop all provide data from 2000 with limited time series,while GHS-POP only utilizes land use data with limited accuracy.In view of the limited remote sensing images of long time series,it is necessary to combine existing multi-source remote sensing data for population spatialization research.In this research,we developed a nighttime light desaturation index(NTLDI).Through the cross-sensor calibration model based on an autoencoder convolutional neural network,the NTLDl was calibrated with the same period Visible Infrared Imaging Radiometer Suite Day/Night Band(VIRS-DNB)data.Then,the geographically weighted regression method is used to determine the population density of China from 1990 to 2020 based on the long time series NTL.Furthermore,the change characteristics and the driving factors of China's population spatial distribution are analyzed.The large-scale,long-term population spatialization results obtained in this study are of great significance in government planning and decision-making,disaster assessment,resource allocation,and other aspects.Wei Guo Jinke Liu Xuesheng Zhao Wei Hou Yunxuan Zhao Yongxing Li Wenbin Sun Deqin Fan 2023International Journal of Digital Earth2023,16,1:0
12From the perspective of experimental practice: High-throughput computational screening in photocatalysis显示文摘Photocatalysis,a critical strategy for harvesting sunlight to address energy demand and environmental concerns,is underpinned by the discovery of high-performance photocatalysts,thereby how to design photocatalysts is now generating widespread interest in boosting the conversion effi-ciency of solar energy.In the past decade,computational technologies and theoretical simulations have led to a major leap in the development of high-throughput computational screening strategies for novel high-efficiency photocatalysts.In this viewpoint,we started with introducing the challenges of photocatalysis from the view of experimental practice,especially the inefficiency of the traditional“trial and error”method.Sub-sequently,a cross-sectional comparison between experimental and high-throughput computational screening for photocatalysis is presented and discussed in detail.On the basis of the current experimental progress in photocatalysis,we also exemplified the various challenges associated with high-throughput computational screening strategies.Finally,we offered a preferred high-throughput computational screening procedure for pho-tocatalysts from an experimental practice perspective(model construction and screening,standardized experiments,assessment and revision),with the aim of a better correlation of high-throughput simulations and experimental practices,motivating to search for better descriptors.Yunxuan Zhao Junyu Gao Xuanang Bian Han Tang Tierui Zhang 2024Green Energy & Environment2024,9,1:0
