摘要: 制备了两组Nafion膜电极(膜中分别分布有带正、负电荷的过渡金属大环配离子),并用循环伏安法研究比较了这两组电极对氧催化还原性能,探讨了配离子和Nafion膜之间的静电作用对电极催化性能影响的规律,同时对其它因素的影响及电荷在Nafion膜中传递的机理也进行了讨论。

关键词: 电催化, 氧还原, Nafion膜电极

Abstract: Two kinds of transition metal macrocyclic complex ions(one with negative charge,the other with positive charge)were incorporated in Nafion coatings respectively in order to make out two groups of Nafion film-coated electrodes. The electrocatalysis of reduction of dioxygen at these electrodes was studied by cyclic voltammetry. The effects of electrostatic interaction between the complex ion and Nafion coating on electrocatalytic performance of film-coated electrodes were approached. The reasons,which result in the significant changes in electrocatalytic performance of Nafion film-coated electrode in comparison to the modified electrode without Nafion coatings are discussed.

Key words: Electrocatalysis, Oxygen reduction, Nafion film-coated electrode
