Surface modulation of MoS2/O-ZnIn2S4 to boost photocatalytic H2 evolution
文献摘要：
To realize the continuous production of hydrogen energy,the efficient photocatalysts are required in the heterogeneous reaction for water splitting.Herein,we reported a surface modulation strategy,via doping oxygen atoms to tune the surface state of ZnIn2S4 nanosheets with cocatalyst MoS2 modification,to enhance water adsorption and surface catalytic reaction for boosting the photocatalytic activity.Consequently,MoS2/O-ZnIn2S4 photocatalysts showed a remarkably superior photocatalytic H2 produc-tion performance of 4.002 mmol g-1 h-1 and an apparent quantum yield(AQY)of～2.53％,5.4 folds higher than ZnIn2S4.Using operando infrared spectroscopy and DFT calculation,we revealed the dynamic struc-tural evolution,as well as the active sites for water adsorption and the catalytic reaction at the MoS2/O-ZnIn2S4 interface.This work reveals the effect of surface modulation on the photocatalytic activity for MoS2/O-ZnIn2S4 and offers a feasible method to devise excellent nanomaterial photocatalysts for H2 production.
