摘      要：Achieving hydrogen production and simultaneous decomposition of organic pollutants through dual-functional photocatalytic reactions has received increasing attention due to the environmentally friendly and cost-effective characteristics of this *** this work,an urchin-like oxygen-doped MoS_(2)/ZnIn_(2)S_(4)(OMS/ZIS)composite was fabricated for the first time using a simple solvothermal *** unique microstructure with abundant active sites and fast charge transfer channels further shortened the charge migration distance and compressed carrier *** obtained composite exhibited an efficient H2 evolution reaction rate of 12.8 mmol/g/h under visible light,which was nearly times higher than pristine ZnIn_(2)S_(4),and the apparent quantum efficiency was 14.9%(420 nm).The results of the simultaneous photocatalytic H2 evolution and organic pollutant decomposition test were satisfactory,resulting in decomposition efficiencies of resorcinol,tetracycline,and bisphenol A that reached 41.5%,63.5%,and 53.0%after 4 h,respectively,and the highest H2 evolution rate was 672.7 umol/g/h for bisphenol ***,natural organic matter(NOM)abundantly found in actual water was adopted as an electron donor for H production under simulated sunlight irradiation,indicating the promising practicability of simultaneous hydrogen evolution and NOM ***,the mechanisms of the dual-purpose photocatalytic reactions,as well as the synergistic effect between the molecular structures of the organic pollutants and the corresponding adsorption behavior on the photocatalyst surface were illustrated in *** obtained results may serve as an inspiration for the rational design of highly efficient,dual-functional photocatalysts in the future.
