title: Synthesis of noble metal/graphene nanocomposites without surfactants by one-step reduction of metal salt and graphene oxide.
abstract: We carried out hydrazine-free, surfactant-free synthesis of noble metal/graphene nanocomposites. The reduction of the noble metals and GO was carried out simultaneously in hot water using ascorbic acid as a reductant. In the noble metal/graphene nanocomposites of Pd, Pt, Au, and Ag nanoparticles, the GO and metal salts were reduced completely by this synthetic method. In addition, the Pd/graphene nanocomposites showed good catalytic activity in the Suzuki coupling reaction and could be reused many times without loss of catalytic activity.
