▎ 摘　　要

The reduction of graphene oxide (GO) can be induced by the photolysis of silver or gold ions under UV light, resulting in the formation of G/M (M=Ag/Au) hybrid nanomaterials. This one-pot reduction method was performed using GO aqueous, solution and silver ammonia solution or chloroauric acid solution under UV light. No additional chemical reductant was involved during the synthetic process. The existence of Ag nanoparticles on the surface of graphene nanosheets and the reduction of GO were characterized by XRD, TEM, SAED, FTIR and XPS. The obtained hybrid nanomaterial exhibits SERS activity and thus has a potential application as SERS substrate. (C) 2012 Elsevier B.V. All rights reserved.
