Nowadays, a major issue about natural water resources protection is the removal of organic pollutants from different industrial sources. In this research, ZnO/BiFeO3 heterojanction nanocomposites have been successfully synthesized and studied by FESEM analysis. The photocatalytic activity of as-prepared samples was evaluated by degradation of RhB as pollutant target under visible light. The pseudo-first-order constants for RhB degradation reaction on the samples reveal that the ZnO/BiFeO3 (30%) heterostructure has excellent photocatalytic ability, which was about 15.3 times as high as the pure ZnO. The enhanced photocatalytic activity could be assigned to the formation of heterojunction at the interface of ZnO and BiFeO3.
