-The catalytic effect of metallic deposits of Pt, Bi, Hg, Au, Pb, Fe and Cu upon the oxidation of hydroquinone on illuminated CdTe electrodes has been studied. The photocurrents and stability factors have also been studied. The photocurrents and stability factors have been found to depend upon the nature of the metals deposited as well as their deposition methods. Those metals that displace the anodic peak potential towards more cathodic values were found to catalyze the oxidation reaction.
