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-WO(3) three-phase electrode has higher I(f)/I(b) 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.
