Abstract
In this study, graphene oxide/CuInS2/ZnO as a new photocatalyst with light absorption properties in the visible region were successfully synthesized via hydrothermal route. The UV–vis absorption spectra of the catalyst suggested that the graphene oxide/CuInS2/ZnO is active under visible light. It was evaluated the photocatalytic activities of graphene oxide/CuInS2/ZnO on the degradation of Rhodamine B under visible light irradiation and was found that the graphene oxide/CuInS2/ZnO obtained exhibit photocatalytic activity higher than single ZnO and CuInS2/ZnO. Presence of graphene oxide with high specific surface area and great conductivity make it as a good support for CuInS2/ZnO and improves removal efficiency for degradation of Rhodamine B.
