Electrocatalytic reduction of dioxygen at the surface of glassy carbon electrodes modified by calix[6]arene-methyl viologen

摘要

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 cyclic voltammograms of the electroreduction of oxygen showed an enhanced current peak at approximately -0.60 V in air-saturated phosphat ebuffer.The experimental parameters were optimized and the metchanism of the catalytic process was discussed.
