Cu2O/GO nanocomposites are successfully synthesized by a facile room-temperature ball-milling assisted solid-state reaction and subsequent heat treatment, using Cu(OH)2CO3, H2C2O4·2H2O and graphene oxide (GO) as the raw materials. The intermediate product Cu2(OH)2n(CO3)1-nC2O4/GO (n=0~1) is firstly formed by milling Cu(OH)2CO3, H2C2O4·2H2O and GO powders at room temperature, then this intermediate product is further heated under the protection of nitrogen atmosphere at 350 ℃ to form Cu2O/GO nanocomposites. This makes it a new promising approach for Cu2O/GO nanocomposites, which is simple and environmentally friendly. The morphology and phase structure of the synthesized products are characterized by field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD). The photocatalytic performances of the obtained products are evaluated by analyzing the degradation of methyl orange (MO) solution under visible-light irradiation. The Cu2O/GO nanocomposites show higher photocatalytic activities than pure Cu2O attributing to the synergistic effect of Cu2O and GO, and the 50Cu2O/GO nanocomposite exhibits a highest efficiency for photocatalytic degradation of MO..
