【摘要】 研究了由阳离子表面活性剂双十二烷基二甲基溴化铵分别和C60或C70在玻碳电极表面形成的膜在0.5mol/LKCl溶液中的电化学,发现在0~-1.0V范围内,有两对峰形较好的还原再氧化峰。实验结果表明,该修饰电极有较好的稳定性和重现性,对三氯乙酸和一氯乙酸的还原,表现出良好的电催化去卤化作用,说明修饰电极上的富勒烯是良好的电子传递媒介体。更多还原

【Abstract】 The electrochemistry of films made from cationic surfactant didodecyldimethylammonium bromide （DDAB） containing C₆0 or C₇0 on a glassy carbon electrode was investigated in an aqueous solution containing 0.5 mol/L KCl, and two couples of reduction/reoxidation peaks for C₆0 or C₇0 were found in the potential range from 0 to -1.0 V. Electrochemically stable fullerene modified electrodes were produced in an aqueous solution. Furthermore, the fullerenes/DDAB film modified electrodes show electrocatalysis towards reduction of chloroacetic acid and trichloroacetic acid, indicating that fullerenes in the films are excellent electron-transfer mediators.更多还原
