Description
Summary:Magnetic photocatalysts utilized in dye wastewater photodegradation field has been attracting lots of attentions due to their convenient recovery and without secondary pollution. Here, rGO is introduced to boost the photocatalytic activity of magnetic photocatalyst β-Bi2O3/SrFe12O19. On the one hand, rGO can promote the migrate of photogenerated carriers and further suppress the recombination of photogenerated charge. On the other hand, the formation of heterojunction structure between β-Bi2O3 and SrFe12O19 can also spur the separation of photoinduced carriers because of the built-in electric field in the heterojunction system. This work will provide reference about the synthesis of high efficiency magnetic photocatalyst and stable magnetic composites.
