Abstract

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
