In this study, Ce0(2) nanowires reduced graphene oxide hybrids (Ce0(2) NWs RGO) were synthesized by a green hydrothermal method using Ce0(2) NWs and graphene oxide (GO) as raw materials. During the process of reduction of GO, hydrothermal condition with supercritical water provides thermal and chemical factors to synthesize RGO. The photocatalytic experimental results show that the Ce0(2) NWs RGO hybrids exhibit enhanced photocatalytic activity for degradation of Rhodamine B (RhB) under UV-light irradiation. It is found that the degree of photocatalytic activity enhancement strongly depends on the mass ratio of RGO in the hybrids, and the remarkable photocatalytic activity is 20 times that of pristine Ce0(2) NWs when the loading amount of RGO is 8.0 wt%. The enhancement of photocatalytic activity can be attributed to the excellently elevated absorption ability for the dye through pi-pi conjugation as well as the effective inhibition of the recombination of photogenerated electrons because of the electronic interaction between Ce0(2) NWs and RGO sheets.
