MoS2修饰ZnIn2S4纳米花的界面效应强化葡萄糖光催化产氢
Enhancement of Glucose Photocatalytic Hydrogen Production by Interfacial Effects in MoS2 Modified ZnIn2S4 Nanoflowers
摘要
Abstract
To enhance the utilization efficiency of sunlight and the separation efficiency of photogenerated carriers,this study constructed MoS2/ZnIn2S4 nanoflower photocatalytic materials via a two-step hydrothermal method,achie-ving efficient photocatalytic hydrogen evolution from glucose.The interaction between MoS2 and ZnIn2S4 after their composite formation was investigated,and its effects on light absorption rate as well as the separation and transport efficiency of photogenerated electron-hole pairs were studied.The study shows that the heterostructure enhances the light-absorbing properties of ZnIn2S4 under visible-light irradiation,thereby increasing the H2 precipitation activity of glucose photocatalysis,and the hydrogen yield of 25-MoS2/ZnIn2S4(with 25 wt％MoS2)is 335.8 μmol/(g·h),which is 11.4 times higher than that of ZnIn2S4;Through density functional theory(DFT)simulations,the charge density distribution at the interface of the MoS2/ZnIn2S4 heterojunction was obtained,which demonstrated charge re-arrangement at the interface and the establishment of a directed built-in electric field from MoS2 to ZnIn2S4.This provides a key driving force for the efficient separation of charge carriers.关键词
