High catalytic performance of Pt nanoparticles via support of conducting polymer for electrooxidation of methanol at carbon ceramic electrode

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 H2SO4...
