用控制电位电解法合成了一种新型的二茂铁甲酸-C60复合材料(FC-C60)。基于其良好的电化学活性，制备了复合修饰玻碳电极。在0.1M NaClO_4溶液中，修饰电极在E_(1/2)=0.32V(vs.SCE)处产生一个可逆氧化波，而在E_(1/2)=−_(0.54V)(vs.Sce)处出现准可逆的C_(60)还原波。电催化研究表明，修饰电极上的FC-C60能催化过氧化氢(H_2O_2)的还原，在1.2mM~21.9 mM范围内线性关系良好，安培法的检出限为2.5×10μ~7M。
A new ferrocenecarboxylic acid–C60composite (Fc–C60) has been synthesized by controlled potential electrolysis. A composite modified glassy carbon electrode has been prepared based on its good electrochemical activity. The modified electrode in 0.1M NaClO4solution shows a reversible oxidation wave at E1/2=0.32V (vs. SCE) attributed to the oxidation of the ferrocene entity and a quasi-reversible reduction wave of C60entity at E1/2=−0.54V (vs. SCE). Electrocatalytic studies show that Fc–C60at the modified electrode can mediate the reduction of hydrogen peroxide (H2O2), and a broad linear range from 1.2μM to 21.9mM for H2O2were obtained with a determination limit of 2.5×10−7M by amperometry.
