The influence of light excitation on the anodic oxidation of a silver electrode in alkaline solutions has been studied. The experimental results have shown that, in addition to the formation of Ag(II) species by a reaction of Ag(I) species with photo-generated holes, illumination in the Ag2O formation region causes the photogeneration of Ag(I) species at the metal/oxide interface. In the presence of ethylene glycol, the so-called current doubling phenomenon was found. This phenomenon has been interpreted in terms of a mechanism involving a catalytic reaction of the glycol with the photogenerated Ag(II) species, and not by a mechanism involving the oxidation of glycol by the photo-generated holes. |
