The physical characterization of these electrodes was carriedout by X-ray diffraction, scanning electron microscopy and energy dispersive X-ray analysis. The meansize of the Pt particles was found to be 10.7 nm. The general aspects of the electrochemical behavior werestudied by cyclic voltammetry in 1 mol L-1 HClO4 aqueous solution.
