In this paper, a composite photocatalytic system Pt-RGO/ZnIn₂S₄-CoPi/BiVO₄ with reduced graphene oxide (RGO) as the electronic relay body was constructed, and its catalytic performance was evaluated by the decolorization of rhodamine B (RhB) and the photocatalytic water decomposition test. In the experiment of photocatalytic removal of RhB, the decolorization rate of RhB reached 99.89% after 3 h. In the process of photocatalytic water splitting, after 5h, the amount of H₂ and O₂ over the composite catalyst system reached 359.6 μmol and 196.3 μmol, respectively. Based on the above data, the working mechanism of the composite photocatalyst system is discussed. It is found that the supper photocatalytic water treatment efficiency is mainly due to RGO acting as a good electron mediator. The main reason is that RGO, as an electron relay body, promotes the conduction of photogenerated electrons between two composite monomers, thus improving the photocatalytic performance of the system.
