Abstract:

g-C₃N₄ nanosheets are synthesized by polymerization method and loaded with Bi₄MoO₉ nanoparticles(NPs)on its surface to prepare Bi₄MoO₉/g-C₃N₄(BMC)heterostructure catalyst. BMC samples are characterized by TEM,SEM,DRS and PL. The photocatalytic performance of BMC is investigated with sulfadiazine(SMT)as the target degradation material. The results show that the photocatalytic activity of BMC-50(50.0% Bi₄MoO₉)is the highest. When the concentration of BMC-50 is 0.5 g·L^-1,SMT could degrade 94.0% within 180 min,which is 17.7 times of the degradation capacity of Bi₄MoO₉. The fabrication of the heterostructure between Bi₄MoO₉ and g-C₃N₄ reduces the recombination of electron-hole pairs and enhances the photocatalytic performance.
