Abstract

The preparation and electrochemical characterization of glassy carbon electrodes modified with calixarene-methyl viologen (MV) were investigated. The intermolecular complex of calix[6]arene and MV has an electrocatalytic effect on oxygen reduction. The influence of pH on the electrochemical behaviors of the modified electrodes was studied, and a pH of 6.8 was chosen as the optimum working medium. The cyclic voltammograms of the electrocatalytic reduction of oxygen showed an enhanced current peak in air- saturated phosphate buffer solution. The experimental parameters were optimized and the mechanism of the catalytic process was discussed.
