Abstract
Graphite-like C3N4 hybridized ZnWO4 photocatalyst is synthesized via a facile chemisorption. The C3N4/ZnWO4 photocatalysts show high efficiency for the degradation of methylene blue (MB) under UV light and visible light irradiation. A loading amount of 5% C3N4 over ZnWO4 leads to an 80% increase in the photocatalytic activity under UV light irradiation. The enhanced photocatalytic performance under UV light irradiation could be attributed to the high separation efficiency of the photogenerated electron-hole pairs. The visible light activity of C3N4/ZnWO4 originates from the injection of excited electrons from the lower unoccupied molecular orbital (LUMO) of C3N4 to the conduction band (CB) of ZnWO4.Keywords
