摘要：A stable polyaniline (PANI) film doped with anthraquinonedisulfonate (AQDS) on glassy carbon (GC) electrode is obtained in acidic solution. The electrochemical behavior of PANI/AQDS film coincides with thee donor-acceptor (DA) intramolecular interaction, while the doped AQDS behaves as a two-electron two-proton transfer process during redox reaction. This GC/PANI/AQDS electrode shows high electrocatalytic activity and irreversible electron-transfer characteristic for O(2) two-electron reduction. Tafel behavior analysis suggests that the oxygen reduction kinetics are different at certain potential regions on this electrode. Possible mechanism of oxygen reduction on the GC/PANI/AQDS electrode points to a similar Schottky diode characteristic.
