A study of the electro-catalytic oxidation of methanol on a manganese dioxide modified glassy carbon electrode

Manganese dioxide modified glassy carbon electrodes prepared by cycling the potential of a glassy carbon electrode in acidic solution exhibited electrocatalytic activity for the oxidation of methanol in acidic media. The methods of cyclic voltammetry (CV) have been employed. The mechanism of methanol oxidation has also been discussed in terms of the formations of intermediates normally encountered in small organics electro- oxidation.
