外文摘要：Reducing carbon dioxide (CO2) as fuel by photocatalysis is one of the effective methods in addressing the issues of fossil fuel crisis and greenhouse effect. Here, a novel p-n heterojunction made up of NiO nanosheets and g-C3N4 nanowires has been effectively fabricated on a large scale for the photocatalytic conversion of CO2 to CO and CH4 The morphologies, structures and composition of the NiO/g-C3N4 were characterized, which confirmed the being of the p-n junction between NiO nanosheets and g-C3N4 nanowires. The improved photocatalytic activities of CO2 reduction over NiO/g-C3N4 can come from the broadened light response range and the formation of the p-n junction that could deter the rapid recombination of electrons and holes. The possible photocatalytic mechanism of CO2 reduction reaction has been presented. Moreover, a novel NiO/g-C3N4 photocatalyst exhibits considerable stability for CO2 reduction.
