Abstract: 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.

Key words: Ethylene glycol, Microwave reduction method, Ethylene glycol oxidation, Pd-Ni/MWCNTs
