| Abstract: | Carbon nonotubes(CNTs) were considered as the potential supports for heterogeneous catalysts, especially for liquid-phase reaction. A novel method for CNTs purification was proposed and a catalyst Pt/CNTs were obtained by using the method. The catalyst was characterized by TEM, XRD, BET and cyclic voltammogram curves and applied to the electrochemical oxidation of methanol. It is found that the purification methods have an obvious influence on the catalytical activities of Pt/CNTs towards the electrochemical oxidation of methanol, and the catalytic performance of the cathodic catalyst Pt/CNTs with CNTs as the support which was obtained by multi-step purification method is much better than that of the catalyst Pt/CNTs obtained by mixed acid oxidation purification |
