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(P2Mo18-C6H6O2/GCCME)，研究了它在0.5mol/L H2SO4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 hydroquinonesupermolecular 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.
