abstract:
In this study, Bi2MoO6/g-C3N4 Z-scheme heterojunction photocatalyst was prepared and characterized by XRD and ultraviolet-visible diffuse reflectance spectroscopy. The crystal structure and light absorption properties of the catalyst were tested. The results show that by doping Bi2MoO6 to form heterojunction, the band gap of g-C3N4 was narrowed and the photocatalytic activity was enhanced. By taking Rhodamine B(RhB) as the target pollutant, the effects of pH on photocatalytic degradation of RhB over Bi2MoO6/g-C3N4 were discussed, which indicates that the degradation efficiency was significantly higher than that over g-C3N4 and the pollutant was completely degraded within 1 h of illumination. Finally, trapping experiment was conducted to identify the main active factor as O-2· free radicals in the photocatalytic process, and the possible photocatalytic degradation mechanism was deduced.
