| 摘 要： | 采用电化学方法在导电基体玻碳（GC）电极上制备了二茂铁－磷钼钨杂多超分子膜电极（Fc8POo6W6／GCCME），研究了它在2．0mol.L^-1H2SO3溶液中的电化学行为，该电极进行估安扫描时，既保持了杂多酸的电化学活性和电催化性能，又具有超分子的电催化效应，它对酸性水溶液中的过氧化氢有电催化原还作用，初步探讨了电催化还原机理。

| Abstract: | Ferrocene-phosphomolybdium tungstic heteropoly acid supermolecular film modified glassy carbon electrodes were prepared by electrochemical method. Their electrochemical behaviors were studied in 2.0?mol/L sulfuric acid. It is found that the modified electrodes not only maintains electrocatalytic character and electrochemical activity of the heteropoly acid, but also have new electrocatalytic property of the supermolecule. The modified electrode shows an excellent electrocatalytic activity to the reduction of hydrogen peroxide in acid aqueous solution. The electrocatalytic mechanism is described. |
