Effect of conditions of formation of composite pyrographite/Nafion-polyaniline-Pt anode upon electrooxidation of methanol

Abstract

The effect of the conditions of formation (regime of formation and sequence of deposition of composite components, pH of the solution) of a multicomponent composite anode including polyaniline, Nafion, and platinum on the activity of such an anode in the course of electrocatalytic oxidation of methanol is studied. An explanation of the observed regularities of platinum and polyaniline codeposition is suggested on the basis of the data on the electrode surface topography obtained using the atomic force microscopy technique.
