Abstract
Pt/C nanoparticle catalysts were synthesized using amphiphilic blocks copolymer as reducing and stabilizing agent by varying the pH value of the reaction mixtures. The property and structure of Pt/C catalysts were explored by transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDS) and X-ray diffraction (XRD). The electrochemical catalytic activity for methanol oxidation of the as-prepared Pt/C hybrid was observed by chronoamperometry, cyclic voltammetry. The catalytic activity of the Pt/C catalysts shows much better than the commercial Pt/C (Johnson Matthey) catalysts for methanol oxidation.
