Abstract

The photo-oxidation of hydroquinone to benzoquinone at thin-film monomeric silicon phthalocyanine and chloro-gallium phthalocyanine electrodes has been studied using the faradaic impedance method. The Randles equivalent circuit was used as a starting point to explain the faradaic impedance behavior of these photoelectrochemical systems. Under illumination, the charge transfer resistance decreased and the double layer capacitance increased. This behavior was consistent with results that have previously been observed by cyclic voltammetry and with the model that was presented in the discussion of photocoulometric measurements on these systems.
