中文摘要：
采用微波加热还原法制备了不同化学计量比的Pd-Ni复合多壁碳纳米管（Pd-Ni/MWCNT）催化剂.通过X射线衍射（XRD）、透射电镜（TEM）和能量散射谱（EDS）等微结构和组成表征表明,所合成的催化剂中Pd-Ni合金具有较小的纳米颗粒以及较好的分散程度.循环伏安（CV）、线性扫描（LSV）、计时电流方法（CA）和交流阻抗（EIS）等测试表明,Pd-Ni（3∶1）/MWCNT催化剂对乙二醇的电化学氧化具有较高的催化活性.
英文摘要：
The MWCNT （multi-walled carbon nanotube） electrocatalysts with different Pd/Ni atomic ratios were prepared by microwave reduction method. XRD, TEM, and EDS measurements were used to characterize the composition, particle size, and crystallinity of the catalysts. It showed that the Pd-Ni nanoparticles supported on MWCNTs were small and well dispersed on the surface of MWCNTs. The electrocatalytic oxidation of ethylene glycol （EG） was studied by cyclic voltammetry （CV）, linear sweep voltammetry （LSV）, chronoamperometry （CA） and electrochemical impendance spectroscopy （EIS）. It was found that the performance of ethylene glycol electro-oxidation on Pd-Ni/MWCNT electrocatalysts with a Pd/Ni atomic ratio of 3：1 was the best.
