【Abstract】 The photo-electro-catalytic oxidation of methanol in acid solution on Pt-Ru modified and unmodified titanium dioxide film electrodes has been studied. The photo-catalysis current of the OTE/TiO₂ electrode and photo-electro-catalysis current of the OTE/TiO₂/Pt-Ru electrode both were three order of magnitude larger than that created by the common electrical oxidation. In addition, the effect of Pt-Ru on the current is described. The electrode sensitized by RuL₂（NCS）₂ showed a broader photoresponse spectral region.更多还原
