| 1 | Analysis of variation trends and causes of aerosol optical depth in Shaanxi Province using MODIS data显示文摘The temporal and spatial variations and causes of aerosol optical depth(AOD)in Shaanxi Province were investigated based on the Moderate Resolution Imaging Spectroradiometer(MODIS)derived aerosol data for the period of March 2000–February 2012.The results showed that the distribution of aerosol was largely affected by topography and local economic activities.Heavy aerosol loading and increasing tendency in AOD was observed in Guanzhong,Hanzhong and Ankang basin,while a reverse tendency was revealed in most other regions.The spatial distribution of aerosol Angstrom wavelength exponent was predominantly related to vegetation coverage in Shaanxi.Airborne dust from ground is an important source of coarse mode aerosols.Vegetation improvement indicated by an increase in normalized difference vegetation index(NDVI)and a reduction in dust weather led to a gradual decrease in coarse mode AOD to the north of Qinling Mountains in Shaanxi,while anthropogenic activities led to an increase in fine mode AOD in other areas except those covered by forests.The main aerosol type gradually shifted to the urban industrial type in Shaanxi. | DONG ZiPeng YU Xing LI XingMin DAI Jin | 2013 | Chinese Science Bulletin2013，58，35： | 8 |

| 6 | Recent advances in bismuth-based photocatalysts:Environment and energy applications显示文摘Photocatalysis is an effective way to solve the problems of environmental pollution and energy shortage.Numerous photocatalysts have been developed and various strategies have been proposed to improve the photocatalytic performance.Among them,Bi-based photocatalysts have become one of the most popular research topics due to their suitable band gaps,unique layered structures,and physicochemical properties.In this review,Bi-based photocatalysts(BiOX,BiVO_(4),Bi_(2)S_(3),Bi_(2)MoO_(6),and other Bi-based photocatalysts)have been summarized in the field of photocatalysis,including their applications of the removal of organic pollutants,hydrogen production,oxygen production etc.The preparation strategies on how to improve the photocatalytic performance and the possible photocatalytic mechanism are also summarized,which could supply new insights for fabricating high-efficient Bi-based photocatalysts.Finally,we summarize the current challenges and make a reasonable outlook on the future development direction of Bi-based photocatalysts. | Sijia Song Zipeng Xing Huanan Zhao Zhenzi Li Wei Zhou | 2023 | Green Energy & Environment2023，8，5： | 0 |
| 7 | 3D flower-like mesoporous Bi_(4)O_(5)I_(2)/MoS_(2)Z-scheme heterojunction with optimized photothermal-photocatalytic performance显示文摘3D flower-like hierarchical mesoporous Bi_(4)O_(5)I_(2)/MoS_(2)Z-scheme layered heterojunction photocatalyst was fabricated by oil bath and hydrothermal methods.The heterojunction with narrow band gap of~1.95 eV extended the photoresponse to near-infrared region,which showed obvious photothermal effect due to the introduction of MoS_(2) with broad spectrum response.MoS_(2) nanosheets were anchored onto the surface of flower-like hierarchical mesoporous Bi_(4)O_(5)I_(2) nanosheets,thereby forming efficient layered heterojunctions,the solar-driven photocatalytic efficiency in degradation of highly toxic dichlorophenol and reduction of hexavalent chromium was improved to 98.5%and 99.2%,which was~4 and 7 times higher than that of the pristine Bi_(4)O_(5)I_(2),respectively.In addition,the photocatalytic hydrogen production rate reached 496.78 μmol h^(-1)g^(-1),which was~6 times higher than that of the pristine Bi_(4)O_(5)I_(2).The excellent photocatalytic performance can be ascribed to the promoted photothermal effect,as well as,the formation of compact Z-scheme layered heterojunctions.The 3D flower-like hierarchical mesoporous structure provided adequate surface active-sites,which was conducive to the mass transfer.Moreover,the high stability of the prepared photocatalyst further promoted its potential practical application.This strategy also provides new insights for fabricating layered Zscheme heterojunctions photocatalysts with highly photothermal-photocatalytic efficiency. | Sijia Song Zipeng Xing Ke Wang Huanan Zhao Peng Chen Zhenzi Li Wei Zhou | 2023 | Green Energy & Environment2023，8，1： | 0 |
| 8 | Double Z-Scheme g-C_(3)N_(4)/BiOI/CdS heterojunction with I_(3)^(-)/I^(-) pairs for enhanced visible light photocatalytic performance显示文摘The g-C_(3)N_(4)/BiOI/CdS double Z-scheme heterojunction photocatalyst with I_(3)^(-)/I^(-) redox pairs is prepared using simple calcination,solvothermal,and solution chemical deposition methods.The photocatalyst comprised mesoporous,thin g-C_(3)N_(4) nanosheets loaded on flower-like microspheres of BiOI with CdS quantum dots.The g-C_(3)N_(4)/BiOI/CdS double Z-scheme heterojunction has abundant active sites and in situ redox I_(3)^(-)/I^(-) mediators and shows quantum size effects,which are all conducive to enhancing the separation of photoinduced charges and increasing the photocatalytic degradation efficiency for bisphenol A,a model pollutant.Specifically,the heterojunction photocatalyst achieves a photocatalytic degradation efficiency for bisphenol A of 98.62%in 120 min and photocatalytic hydrogen production of 863.44 mmol h^(-1) g^(-1) on exposure to visible light.The excellent visible-light photocatalytic performance is as a result of the Z-scheme heterojunction,which extends absorption to the visible light region,as well as the I_(3)^(-)/I^(-) pairs,which accelerate photoinduced charge carrier transfer and separation,thus dramatically boosting the photocatalytic performance.In addition,the key role of the charge transfer across the indirect Z-scheme heterojunction has been elucidated and the transfer mechanism is confirmed based on the detection of intermediate I_(3)^(-)ions.Thus,this study provides guidelines for the design of indirect Z-scheme heterojunction photocatalysts. | Yan Zhang Yixiao Wu Liang Wan Wenfeng Yang Huijun Ding Chongyang Lu Weihao Zhang Zipeng Xing | 2022 | Green Energy & Environment2022，7，6： | 0 |
