Copper chloride dihydrate was used as copper source and thioacetamide was used as sulfur source.Nano-CuS was prepared by water bath method at 65℃,then CuS/RGO nanocomposites were prepared by mixed nano-CuS with GO at 180℃ by hydrothermal method,while ascorbic acid was added as reducing agent.All composites were characterized by XRD,XPS,Raman,SEM,BET,UV-Vis,and the photocatalytic activity of nano-CuS,RGO and CuS/RGO was evaluated by degradation of methylene blue under xenon lamps(150W) irradiation.The results showed that the nano-CuS was evenly composed with the RGO,and the specific surface area of the composite was 66.5m2/g,and the UV-Vis showed a outstanding visible light absorption performance.The degradation rate of 0.03g CuS,RGO,and CuS/RGO was 38.4%,21.3%,78.5% after 120min irradiation.The degradation rate of 0.1g CuS/RGO reached 98.6% after 120min of irradiation,which indicated that the introduction of RGO greatly improved the photocatalytic property of CuS in the visible light region.
