A simple approach was proposed to fabricate tungsten carbides/graphitic carbon（WxC/GC） composites by using ion-exchange resin as carbon resource，ammonium metatungstate(AMT) as tungsten source and the potassium ferrocyanide（K4Fe(CN)6·3H2O）as catalyst. The resin-based precursor was prepared via the ion-exchange method and underwent reduction and synchronous carbonization at high temperature under N2 atmosphere to fabricate WxC/GC composites. Furthermore, the WxC/GC supported platinum nanoparticle (Pt/WxC/GC) was prepared by microwave-assisted polyol method. The crystalline phase，structure and morphology of samples were characterized with X—ray diffraction(XRD)，transmission electronic microscope(TEM)，and energy dispersive X-ray spectroscopy(EDS)．The electro-catalytic activity of Pt/WxC/GC in acidic media was investigated using cyclic voltammetry. The results indicated that WxC particles were uniformly distributed in the as-synthesized WxC/GC composites with the size of 2～30nm. Pt/WxC/GC with 10wt% Pt exhibits attractive catalytic activity and stability, the oxidation current density of methanol can reach 39mA·cm-2.
