Abstract: Reduced graphene oxide-platinum (rGO-Pt) nanocomposites were produced by high temperature synthetic process from the graphene oxide and H2PtCl6. Transmission electron microscopy and micro-spectrum results showd that Pt nanoparticles with a average diameter of 30 nm were uniformly distributed on the rGO surface. The Pt nanoparticles had porous structure with good crystallinity. GO was transferred to rGO at high temperature. With the similar method, rGO-Au or rGO-Ag nanocomposites could also be prepared, and the resulted composites exhibit typical surface plasmon resonance adsorption against visible light. In this method, oleylamine acted as solvent, reduction agent for metal salt and surfactant simultaneously. The synthetic process is simple, rapid, and has wide practical application prospect.
