A comparison between different novel carbon supported platinum nano-catalysts for Methanol oxidation reaction

In this study, a reduced graphene oxide and a nitrogen-doped graphene-based platinum catalyst were prepared and compared to a commercial Pt/C catalyst. X-ray diffraction patterns were recorded in order to prove successful synthesizing of graphene oxide. Scanning electron microscopic pictures were taken to show the surface and morphology of graphene-based catalysts. Excellent distribution of doped heteroatoms of nitrogen and platinum nanoparticles was showed by elemental mapping and a standard three-electrode half-cell method was employed to measure electrochemical characteristics of under investigation catalysts. To evaluate the electrochemically active surface area a CO-stripping method was used. As a result, the N-doped graphene-based catalyst showed a phenomenon performance towards methanol oxidation reaction (MOR).
