主　　题：Ag/Ag_2O/BiVO_4 Tetracycline hydrochloride Photocatalytic degradation Pharmaceutical micropollutants 

摘      要：The degradation of pharmaceutical micropollutants is an intensifying environmental problem and synthesis of efficient photocatalysts for this purpose is one of the foremost challenges ***,this study was conducted to develop novel plasmonic Ag/Ag2O/BiVO4 nanocomposite photocatalysts by simple precipitation and thermal decomposition methods,which could exhibit higher photocatalytic activity for mineralized pharmaceutical *** the different treatments,the best performance was observed for the Ag/Ag2O/BiVO4 nanocomposites (5 wt.%;10 min’s visible light irradiation)which exhibited 6.57 times higher photodegradation rate than the pure ***,the effects of different influencing factors on the photodegradation system of tetracycline hydrochloride (TC-HCl) were investigated and the feasibility for its practical application was explored through the specific light sources,water source and cycle *** mechanistic study demonstrated that the photogenerated holes (h^+),superoxide radicals (·O2^-)and hydroxyl radicals (·OH) participated in TC-HCl removal process,which is different from the pure BiVO4 reaction ***,the present work can provide a new approach for the formation of novel plasmonic photocatalysts with high photoactivity and can act as effective practical application for environmental remediation.
