Facile synthesis and enhanced photocatalytic activity of a novel FeVO4/Bi4O5Br2 heterojunction photocatalyst through step-scheme charge transfer mechanism

Construction of a step-scheme (S-scheme) heterojunction photocatalyst is currently under investigation as it is known to facilitate a decrease in the e–/h+ recombination rate and preserves a strong redox ability. This research work has reported on the use of microwave irradiation combined with the wet impregnation synthesis of FeVO4/Bi4O5Br2 heterojunctions at different weight percentages (%wt) of FeVO4 (0.5%, 1%, 3% and 5%wt).
