We developed a solvothermal process by a facile refluxing for growing graphitic-carbon nitride (g-C3N4) polymer on graphene oxide (GO) to form a three-dimensional (3D) flake-like g-C3N4 on reduced GO (g-C3N4@RGO) hybrid material. As catalysts in direct methanol fuel cells (DMFCs), the Pt/g-C3N4@RGO exhibited high electrochemically active surface area (ECSA) (76.2m2/g), effective electrocatalytic oxidation of methanol(13.5mA/cm2), CO poison tolerance (If/Ib= 1.48), reliable stability compared with Pt/RGO, Pt loaded Vulcan XC-72 (Pt/C), and Pt loaded graphite (Pt/Gr). These results demonstrate that the as-synthesised g-C3N4@RGO hybrid material could be a promising candidate as a high performance catalyst supports for a fuel cell application. |
