摘要: 本文研究二茂铁衍生物——硬脂酸二茂铁酯(FcOCOC17H35)L-B膜技术修饰SnO2电极的循环伏安性能.实验结果用电极表面吸附(修饰)分子的表面活度理论进行计算机拟合和此较,实验数据与理论符合较好.进一步求得修饰分子的标准电极电势和修饰量。结果表明硬脂酸二茂铁酯L-B膜电化学性能稳定,可逆性较好,可以作为快速电荷转移的修饰电极材料。

Abstract: The cyclic voltammetic behavior of ferrocene derivative——ferrocenyl-n-octadecanoate (Fc-OCOC17H35) which was attached on SnO,electrode surface by L-B technique was studied.Surface activity theory of molecules absorbed (modified) on electrode surface was employed to compare with the experimental cyclic voltammograms using a computer-fitting approach.Quantitative agreement between experiment and theory was obtained and some parameters such as standard electrode potential,cone,of attached reactants were estimated The results indicated that L-B film of FcOCOC17H35 can act as stable,reversible and fast charge transfer agent for modified electrodes.
