摘要
采用电化学方法在导电基体玻碳 (GC)电极上制备出Dawson型磷钼杂多酸对苯二酚超分子膜电极 (P2 Mo1 8-C6 H6 O2 GCCME) ,研究了它在 0 .5mol LH2 SO4溶液中的电化学行为 ,实验表明该电极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 ,对酸性溶液中 L -半胱氨酸具有电催化氧化作用 .初步探讨了电催化氧化机理 .
Dawson molybdophosphoric heteropoly acid and hydroquinone supermolecular film modified electrodes were prepared by electrochemical method. Their electrochemical behaviors were studied in 0.5?mol/L sulfuric acid. It is found that the modified electrodes not only maintains electrocatalytic activity of modified electrodes, but also have new electrocatalytic property towards the oxidation of L-cysteine in acid aqueous solution. The electrocatalytic mechanism is described.
