    Abstract:

    In this paper, CeO2 with a pore size distribution range of 3.1~4.2nm and a specific surface area of 174.72m2/g was prepared as a co-catalyst by hydrothermal method. PtNiCeO2/C catalyst was prepared by microwave assisted glycol method using carbon nanotubes as carrier. Effect of Ni addition on electrocatalytic performance of Pt based catalysts. The prepared CeO2 and the catalyst were characterized by X-ray diffraction (XRD), BET, SEM and EDAX. The prepared catalyst was characterized by electrochemical workstation electrochemical performance test. The results show that the electrocatalytic activity of CeO2 catalyst prepared by adding CeO2 and the ratio of Pt to Ni is 5:1, the electrocatalytic activity is 90.41m2/g and the peak current density is 837.67A/g, 1100s steady-state current density of 178.33A/g, indicating that adding a certain amount of Ni, can improve the catalyst anti-toxic and electrocatalytic performance.
