| Abstract: | The electrocatalysis oxidation reaction of the catalitic electrochemically synthesized polypyrrole film to the ascorbic acid in aqueous solution is studied. The cyclic voltammograms indicate that the oxidative peak potential of ascorbic acid on the polypyrrole film electrode shift more than 400 mV to the minus. The effects of the value of pH, scan rate and thickness of the film on the catalysis are also discussed. |
