FUNGARO, D. A.; OLIVEIRA-NETO, A.  e  LINARDI, M.. Electrocatalytic oxidation of ethanol on platinum nanoparticles modified polyaniline electrode. Lat. Am. appl. res. [online]. 2007, vol.37, n.3, pp.223-226. ISSN 0327-0793.

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.
