A facile method was used for the preparation of Pt nanoparticles supported on graphene/Vulcan XC-72 carbon (denoted as Pt/Gr-C) by co-reduction of graphene oxide (GO) and H2PtCl6 with subsequent incorporation of Vulcan XC-72 carbon between graphene. The catalyst is extensively characterized by using scanning electron microscope (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD),...
Direct methanol fuel cells (DMFCs) have recently become the research hotspot, due to their high energy-conversion efficiency, low operating temperature, and low exhaust emission. In this study, PtCo nanoalloys supported on reduced graphene oxide (RGO) were successfully synthesized via a one-step reduction method, carried out by coreduction of PtCl62−, Co2+ and graphene oxide (GO) in ethylene glycol...
