Abstract
Oxidation and reduction processes of silver‐silver oxide electrodes were studied, especially the influence of light excitation on these processes. The experimental results have shown that light absorption by silver (I) oxide leads to an anodic oxidation to silver (II) oxide. The electrochemical reduction of silver (II) oxide formed during illumination is considerably inhibited. A possible mechanism explaining the photoelectrochemical processes and the inhibition is discussed.
