Graphene nanosheet (GNS) supported Pt nanoparticles are prepared using perfluorosulfonic acid (PFSA) as a functionalization and anchoring agent. Transmission electron microscope (TEM) results indicate that the prepared Pt nanoparticles are uniformly deposited on GNS with a narrow particle size ranging from 1 to 4 nm in diameter. A high catalytic activity of this novel catalyst is observed by both the cyclic voltammetry and oxygen reduction reaction (ORR) measurements due to the increasing of proton (H+) transmission channels. As a result, through polymer functionalization Pt nanoparticles with small size can be highly dispersed on the GNS surfaces.
