【Abstract】 Objective: To investigate the preparation of poly-copper tetraaminophthalocyanine film synthesized in the presence of ferrocene (PPcFc) and the electro-catalytic oxidation of ascorbic acid on PPcFc. Methods: The PPcFc film was prepared by electroploymerization on glass carbon electrode. The electro-catalytic property of PPcFc film in buffer solution was studied by using cyclic voltammetry. Results: The oxidation potential of ascorbic acid on glass carbon modified PPcFc was lowered by 270 mV in the negative direction compared with that on galss carbon unmodified. Conclusion: PPcFc has better catalytic activity in the oxidation of ascorbic acid.更多还原
