▎ 摘　　要

Three-dimensional porous CuS/graphene photocatalysts had been successfully prepared by twostep solvothermal method and exhibited outstanding adsorption synergistic photodegradation for anion dyemethyl orange (MO). Due to the combination of the adsorption of graphene porous aerogel and the photocatalysis of CuS, the CuS/graphene photocatalysts could rapidly enrich the methyl orange and effectively degrade MO in suit. The degradation rate of MO went up to as high as 92.94% by the CuS/graphene composites in 55 min through the synergistic effect of adsorption photocatalytic, which was about 2.9 times more than that of bare CuS. The obviously improved photodegradation rate was attributed to the excellent adsorption performance and high charge mobility of the porous graphene substrate. Moreover, its MO removal efficiency still remained 79.47% after 3 times cyclic experiments. Meanwhile, due to its special 3D porous network structure, the CuS/graphene composites could efficiently separate from the solution without assistance of filtering. Therefore, the CuS/graphene composites with the synergy of adsorption and photocatalysis would be a promising strategy for practical dye wastewater treatment.
