In this work graphene nanosheets (GNSs), which act like both single-layer graphene and highly graphitic carbon reported as a support material for Pt nanoparticles for oxygen reduction in fuel cells. Pt nanoparticles are deposited on graphenes protected by Polyvinyl pyrrolidone (PVP) and acrylamide/β methacryl-oxyethyl-trimethyl-ammonium (Superfloc C-442), and characterized with transmission electron microscopy, X-ray diffraction, Raman spectroscopy, and electrochemical tests. Pt/GNS exhibits greatly enhanced electrochemical performance than commercial (Electro Chem Pt/C). These are attributed to the much graphitized degree of GNS in compared to carbon black and the enhanced Pt-carbon interaction in Pt/GNS.
