Electrodeposition Of Platinum Nanoparticles On Polyaniline Modified Electrode And Its Electrocatalytic Activity Towards The Oxidation Of Methanol

In this research, we reported the electrosynthesis of platinum nanoparticles on Polyaniline (PAni) modified electrode. The modified electrodes were prepared by incorporation of aniline and platinum salt [H-2 (PtCl6), 6H(2)O] in phosphoric acid medium with KCl solution on composite graphite (CG) surface via cyclic voltammetry (CV) method. The synthesized platinum nanoparticles were characterized by using scanning electronic microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX). The electro oxidation of methanol was investigated at the surface of these modified electrodes using CV method. It was found that methanol was oxidized with platinum embedded on the surface of PAni modified electrodes during the anodic potential sweep. Moreover, several impact factors such as scan rate, potential and concentration of methanol were studied on the oxidation of methanol toward electrosynthesized electrodes.
