Synthesis of Graphene oxide/ZnO nanocamposite as a photocatalyst for degradation of Rhodamine B

We developed a facile method for preparation of Graphene oxide/ ZnO, as a photocatalyst, by hydrothermal process. The UV-Vis absorption spectra of the catalyst suggested that the Graphene oxide/ ZnO is active under visible light. We evaluated the photocatalytic activities of graphene oxide/ZnO on degradation of Rhodamine B under visible light irradiation and found that the Graphene oxide/ZnO obtained exhibit photocatalytic activity higher than single ZnO. Presence of Graphene oxide with high specific surface area and great conductivity makes it a good support for ZnO and improves removal efficiency for degradation of Rhodamine B.
