| 1 | Photocatalytic defluorination of perfluorooctanoic acid by surface defective BiOCl:Fast microwave solvothermal synthesis and photocatalytic mechanisms显示文摘There is an urgent need for developing cost-effective methods for the treatment of perfluorooctanoic acid(PFOA)due to its global emergence and potential risks.In this study,taking surface-defective BiOCl as an example,a strategy of surface oxygen vacancy modulation was used to promote the photocatalytic defluorination efficiency of PFOA under simulated sunlight irradiation.The defective BiOCl was fabricated by a fast microwave solvothermal method,which was found to induce more surface oxygen vacancies than conventional solvothermal and precipitation methods.As a result,the asprepared BiOCl showed significantly enhanced defluorination efficiency,which was 2.7 and33.8 times higher than that of BiOCl fabricated by conventional solvothermal and precipitation methods,respectively.Mechanistic studies indicated that the defluorination of PFOA follows a direct hole(h^+)oxidation pathway with the aid of·OH,while the oxygen vacancies not only promote charge separation but also facilitate the intimate contact between the photocatalyst surface and PFOA by coordinating with its terminal carboxylate group in a bidentate or bridging mode.This work will provide a general strategy of oxygen vacancy modulation by microwave-assisted methods for efficient photocatalytic defluorination of PFOA in the environment using sunlight as the energy source. | Yuanyuan Sun Guiying Li Wanjun Wang Wenquan Gu Po Keung Wong Taicheng An | 2019 | Journal of Environmental Sciences2019，31，10： | 7 |
| 2 | Single atom catalytic oxidation mechanism of formaldehyde on Al doped graphene at room temperature显示文摘Formaldehyde(HCHO) is one kind of common indoor toxic pollutant,the catalytic oxidation degradation of formaldehyde at room temperature is desired.In this work,a new single atomic catalyst(SAC),Al doped graphene,for the catalytic oxidation of HCHO molecules was proposed through density function theory(DFT) calculations.It is found that Al atoms can be adsorbed on graphene stably without aggre s sion.Then HCHO can be effectively oxidized into CO2 and H2 O in the presence of O2 molecules on Al doped graphene with a low energy barrier of 0.82 eV and releasing energy of 2.29 eV with the pathway of HCHO→HCOOH→CO→CO2.The oxidation reaction can happen promptly with reaction time τ=56.9 s at the speed control step at room temperature.Therefore,this work proposed a high-performance catalyst Al-doped graphene without any noble metal for HCHO oxidation at ambient temperature,and corresponding oxidation pathway and mechanism are also deeply understood. | Guanlan Liu Jtmhui Zhou Weina Zhao Zhimin Ao Taicheng An | 2020 | Chinese Chemical Letters2020，31，7： | 3 |
| 3 | The source and transport of bioaerosols in the air:A review显示文摘Recent pandemic outbreak of the corona-virus disease 2019(COVID-19)has raised widespread concerns about the importance of the bioaerosols.They are atmospheric aerosol particles of biological origins,mainly including bacteria,fungi,viruses,pollen,and cell debris.Bioaerosols can exert a substantial impact on ecosystems,climate change,air quality,and public health.Here,we review several relevant topics on bioaerosols,including sampling and detection techniques,characterization,effects on health and air quality,and control methods.However,very few studies have focused on the source apportionment and transport of bioaerosols.The knowledge of the sources and transport pathways of bioaerosols is essential for a comprehensive understanding of the role microorganisms play in the atmosphere and control the spread of epidemic diseases associated with them.Therefore,this review comprehensively summarizes the up to date progress on the source characteristics,source identification,and diffusion and transport process of bioaerosols.We intercompare three types of diffusion and transport models,with a special emphasis on a widely used mathematical model.This review also highlights the main factors affecting the source emission and transport process,such as biogeographic regions,land-use types,and environmental factors.Finally,this review outlines future perspectives on bioaerosols. | Wenwen Xie Yanpeng Li Wenyan Bai Junli Hou Tianfeng Ma Xuelin Zeng Liyuan Zhang Taicheng An | 2021 | Frontiers of Environmental Science & Engineering2021，15，3： | 2 |
