Reduced graphene oxide (RGO)/silver nanoparticle (Ag NP) composites (Ag/RGO) were prepared by a two-step route that involves chelating Ag NPs onto GO in the presence of N, N-dimethylformamide, followed by reduction with sodium borohydride. Ag NPs with an average dimeter of 5.6 nm were found to be uniformly distributed on the surface of RGO sheets, and the resulting Ag/RGO composite exhibits good chemical catalytic behavior toward reduction of methylene blue and high electrocatalytic activity toward electrooxidation of hydrazine.
