Photocatalytic CO2 reduction driven by solar light is a green approach that can decrease the greenhouse effect induced by high CO2 concentration in the atmosphere and generate carbon-based chemicals/fuels as well.In this paper,non-metal co-catalysts ZnO/ZnS type-Ⅱ hetero-junction nanoparticles with a rough surface were prepared through a hydrothermal process.When used as a photocatalyst for CO2 reduction,the optimal one showed good cycle stability and a higher yield rate of 27.8 μmol·g-1·h-1 for CO2 conversion into CO.The outstanding catalytic activity originated from the rich interfaces between ZnO and ZnS in the nanoscale could significantly reduce the delivery path of carriers and improve the utilization efficiency of photo-excited electron/hole pairs and the enriched surface oxygen defects could supply much more reaction active sites for CO2 adsorption.
