Construction Of Full Spectrum-Driven Csxwo3/G-C3n4 Heterojunction Catalyst For Efficient Photocatalytic Co2 Reduction
APPLIED SURFACE SCIENCE(2021)
Abstract
Full spectrum-driven CsxWO(3)/g-C3N4 catalyst was successfully synthesized by the combination of solvothermal and ultrasonication methods and used in CO2 photocatalytic reduction. The experimental results suggested that 20 wt% CsxWO3/g-C3N4 catalyst possessed the best yield of CH4 under NIR and full spectrum light irradiation, which were 1.72 and 6.79 mu mol.g(-1).h(-1), respectively. This outstanding photocatalytic activity could be attributed to the localized surface plasmonic resonance effect and the formation of heterojunction structure, which led to the improved charge separation efficiency, good light-harvesting ability and broadened light response.
