  • Abstract In this study, the multi-walled carbon nanotubes (MWCNTs) with high thermal
    conductivity and surface area are used as a supporter of Pt and bimetallic Cu-Pt
    nanocomposite, which are catalysts for anode material in fuel cell.
    Cu-Pt nanocomposite with different ratios of Cu and Pt are synthesized on
    MWCNTs by polyol method. The structures and morphologies of nano hybrid
    catalysts are analyzed by XRD, FESEM and TEM. According to the XRD patterns
    of Cu-Pt/MWCNTs, Pt and Cu form the solid solution structure, by polyol process,
    the average diameters of Pt and Cu-Pt nanoparticles on MWCNTs can be controlled
    within 3-10 nm and 5-15 nm, respectively. The electrocatalytic behavior during
    methanol oxidation reactions have been investigated by Cyclic Voltammetry (CV).
    According to the results the methanol electrooxidation activity of Pt/MWCNTs is
    higher than that of Pt/carbon black but lower than that of Cu-Pt/MWCNTs. The
    enhancement of the methanol oxidation activity of Cu-Pt/MWCNTs may relate to the
    bimetal structure and the interaction between Cu and Pt., the performance of
    Cu-Pt/MWCNTs system in electro catalysis reaction is 100% higher than
    Pt/MWCNTs system. In indicates that added Cu improves dramatically on the
    performance of Pt/MWCNTs catalysts in electrocatalytic reaction.
