Electrocatalytic oxidation of ethanol on platinum nanoparticles modified polyaniline electrode

the electrocatalytic properties of platinum nanoparticles incorporated into polyaniline films was investigated for oxidation of ethanol in sulfuric acid solutions. the electropolymerization of aniline and the electrochemical depositions of plati-num particles into the polyaniline film were achieved by cyclic voltammetry. the effect of the formation conditions of platinum-modified polyaniline films (as cycle numbers, sweep rates) and alcohol concentra-tion were evaluated. the platinum-modified polyani-line films formed by the optimization conditions can be used as a convenient conducting substrate for the ethanol electrooxidation.
