- Abstract
Carbon ceramic electrode (CCE), a new electrode substrate, was prepared by sol-gel procedure and used for the electropolymerization of aniline and dispersion of platinum nanoparticles into the resulting polyaniline (PANI) film. The microscopic structure and morphology of the CCE, CCE/PANI and CCE/PANI/Pt are characterized by scanning electron microscopy. The electrochemical and catalytic activities of the CCE/PANI/Pt were studied in 0.3 M HSO solution. The electrocatalytic oxidation of methanol at the CCE/PANI/Pt has been investigated using cyclic voltammetric and chronoamperometric methods. The catalytic activity of Pt-coated PANI film on the CCE surface was compared with glassy carbon and Pt polyaniline/platinum-modified electrodes.
