摘要：
Bi2MoO6/WO3 composite photocatalysts with various Bi2MoO6 amounts were successfully synthesized by hydrothermal method. The microstructure, morphologies, optical absorption properties and spectral response of Bi2MoO6/WO3 composites were measured and characterized by XRD, SEM, UV-Vis, EIS and PL. Moreover, the photocatalytic activities of the samples were further investigated. The results show that the photocatalytic activity of the 15%Bi2MoO6/WO3 composite is obviously higher than that of the pure WO3 and Bi2MoO6: the photocatalytic oxygen production efficiency of the Bi2MoO6/WO3 is 2.3 times that of the pure WO3. The oxygen production efficiency of composite catalyst obtained 107 μmol/(g·h) after introducing Fe(NO3)3·9H2O assacrificial agent and exhibited good cycling stability. It is inferred that the Bi2MoO6 nanoparticle-WO3 nanorod heterojunction structure improves the transport and transfer efficiency of photo-generated carriers, reduces the recombination probability of electron-hole pairs, which is helpful to enhance the photocatalytic activity.
