摘　　要：将Pd纳米颗粒负载在功能化的多壁碳纳米管(MWCNTs)上制备出Pd/MWCNTs催化剂。应用TEM、XRD对其进行表征,并利用循环伏安(CVs)、时间电流法检测其对碱性溶液中甲醇的催化活性。结果表明,Pd纳米颗粒高分散在功能化的多壁碳纳米管上,在碱性溶液中Pd/MWCNTs催化剂对甲醇显出了高的催化活性和稳定性。The funetionalized multi-walled carbon nano-tubes （MWCNTs） were prepared on Pd nano-particles. The eletrocatalyst was characterized by transmission electron microscopy （TEM）, X-ray diffraction （XRD）. The catalytic activity for methanol oxidation in alkaline media was studied by cyclic voltammograms （CVs） and chronoamperometry. The results show that Pt nano-partieles highly disperse on the MWCNTs surface. The Pd/MWCNTs catalyst exhibites high catalytic activity and stability. The Pd/MWCNTs catalyst has a promising application in alkaline direct methanol fuel cells （DMFC）.
