【Abstract】 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.更多还原
