Synergy effect of nanostructure electrodes supported by tungsten carbide and oxide for methanol electrooxidation

We report nanostructure electrodes for methanol electrooxidation by means of the co-sputtering deposition method. The Pt-WC-WO3 three-phase electrode has higher If/Ib and oxidation current density i.e. improved electrocatalytic activity in comparison with those of pure Pt and two-phase electrodes because of both catalysis of tungsten carbide and size-control by tungsten oxide.
