The electrooxidation of methanol on porous carbon electrodes impregnated with bimetallic platinum group catalysts, Pt/M (M = Au, OS, Ir, Pd and Ru), in a H,SO, electrolyte is reported. Both Au and Pd are found to inhibit the reaction while Ir, OS and Ru act as promotors. The presence of metal oxides
High-activity platinized-carbon anodes for methanol oxidation have been prepared. XPS investigation of the electrodes showed the presence of both Pt" and oxidized Pt species. The enhanced activity of these electrodes, compared with Pt black, can be explained in terms of the unusual surface propertie
