Copper/graphene composite materials were fabricated by hydrothermal method, and its structure and morphology were characterized by XRD, FTIR, SEM and TEM, the catalytic performance of this composite toward methylene blue was investigated at hydrogen peroxide solution. The results shown that the copper particles size were small and uniform distribution loading graphene sheets in the composite material, which exhibits good catalytic activity for the decolorization of methylene blue, the 0.18 g.L-1 composite catalyst with in 300 min on the decolorization rate of methylene blue can reach 90.7%, after 5 cycles on the catalytic efficiency of methylene blue test is still more than 88.0%.
