摘要：
In this study a rapid microwave heating method was used to prepare the graphene supported platinum-tungsten catalysts with the different Pt:W molar ratios. The prepared catalysts were characterized by means of Transmission Electron Microscopy and Inductively Coupled Plasma Optical Emission Spectroscopy. The electrocatalytic properties of the PtW/GR catalysts towards the oxidation of borohydride in an alkaline medium were investigated by means of cyclic voltammetry and chrono-techniques. It was found that the graphene supported platinum-tungsten catalysts with the Pt: W molar ratios equal to 1.6:1, 2.4:1 and 7.1:1 were prepared. The synthesized PtW/GR catalysts with the different Pt: W molar ratios show an enhanced electrocatalytic activity towards the oxidation of H-2 generated by catalytic hydrolysis of BH4- and direct oxidation of BH4- comparing with the graphene supported bare W catalyst.
