CdS/Graphene nanocomposites with phptocatalytic activity were prepared by interfacial self-assembly successfully. The morphology, microstructure and photocatalytic activity of nanocomposites were characterized by XRD、SEM、TEM、UV-Vis. The results show that the synthesis procedure of interfacial reaction is simple, and the as-prepared nanocomposites have an excellent photocatalytic activity for the degradation of methyl orange with a maximum degradation rate of methyl orange more than 94% in 40 min under visible light.
