摘要：
The novel Bi2WO6/r-GO/Bi25FeO40 Z-scheme system composite photocatalyst was synthesized by hydrothermal method. The crystal structure, elemental composition, surface morphology, optical and photoelectrochemical properties of the synthesized composite photocatalyst were tested. Compared with pure Bi2WO6, Bi25FeO40 and Bi2WO6/Bi25FeO40, Bi2WO6/r-GO/Bi25FeO40 composite photocatalyst has good degradation effect on methylene blue under visible light irradiation for 30 min. The synthetic Bi2WO6/r-GO/Bi25FeO40 photocatalyst norfloxacin also has a certain degradation capacity. The effects of catalyst dosage and norfloxacin concentration on the degradation were investigated. The catalytic mechanism of Bi2WO6/r-GO/Bi25FeO40 composite photocatalyst can be well explained by the Z-scheme system. The results show that the effective charge separation, better light absorption and larger surface area of Bi2WO6/r-GO/Bi25FeO40 composite photocatalyst contribute to excellent photocatalytic performance.
