Surface plasmon resonance induced synthesis of Ag/graphene composites from Ag/graphene oxide (Ag/GO) in a two-phase (water-toluene) solvent was reported. Transmission electron microscopy (TEM) results revealed that the Ag nanoparticles with size of 5-8 nm were trimly distributed on reduced graphene oxide sheets. Raman and X-ray photoelectron spectroscopy (XPS) have demonstrated low defect density and high deoxygenation degree of graphene in Ag/graphene composite. The excellent structure and morphology of Ag/graphene composites contributed to superior electrical properties for reduction of H2O2. (c) 2012 Elsevier B.V. All rights reserved.
