摘要：
Competitive photoelectrochemical oxidation of a variety of reducing agents at the TiO2 single crystal photoanode was investigated by means of the rotating ring-disk electrode technique. The competitive oxidation phenomena can be elucidated based on the redox potentials of electroactive species. A reducing agent with a more negative redox potential is oxidized in preference to others. Both the pH dependence of competitive oxidation and stability of the TiO2 photoanode are explained, based on charge transfer with participation of the surface states, focusing upon the redox potentials. © 1979, American Chemical Society.
