Electrocatalytic Oxidation of Ethanol on Graphite Electrodes Coated with a Nafion Film with Incorporated Particles of Ruthenium or Its Complexes

The electrochemical behavior of ethanol on graphite electrodes with a Nafion film containing ruthenium as a crystalline metal deposit or a metal complex was compared. It was found that, in the oxidation of ethanol, aqua and phenanthroline complexes of ruthenium(III) incorporated in the Nafion film exhibit catalytic activity. A larger catalytic effect was observed at an electrode containing the Ru(phen)₃³⁺ complex. A procedure is proposed for the voltammetric determination of ethanol at this electrode.__________Translated from Zhurnal Analiticheskoi Khimii, Vol. 60, No. 6, 2005, pp. 603–609.Original Russian Text Copyright © 2005 by Shaidarova, Gedmina, Chelnokova, Budnikov.Presented at the VI All-Russian Conference (with International Participation) on Electrochemical Methods of Analysis (EMA-2004, Ufa, May 23–27, 2004).
