| Abstract: | Pt/CeO2/CNTs catalysts were prepared by a microwave-assisted polyol approach in order to investigate the effect of the addition of CeO2 with different weight ratios to Pt/CNTs catalysts on electrochemical oxidation of methanol in alkaline solution.The X-ray diffraction(XRD) and transmission electron microscopy(TEM) results showed that the Pt particles were dispersed uniformly on the CeO2/CNTs supports and Pt particles were smaller.The cyclic voltammetry and chronoamperometry results indicated that the catal... |
