Abstract

Polyaniline was eleetrodeposited on platinum and semiconducting (Cd-chalcogenides, Si, GaAs, GaP) electrodes from aqueous solution (pH = 1) containing aniline. The electrochemical behavior of such films was examined in aqueous and nonaqueous solutions by cyclic voltammetry. Results show that the polyaniline film is conducting in both cathodic and anodic regions at pH < 3 as evidenced by the electrochemical redox reactions of various redox couples on polyaniline-coated electrodes. In general, all polyaniline-coated semiconductor electrodes examined in this work exhibited enhanced stability of the photocurrent when compared to that of the naked electrodes.
