▎ 摘　　要

Using graphene as the carrier and ethylene glycol as the reducing agent, a Pt(100) crystal face preferential orientation catalyst was synthesized by oil bath method with adding different additives as shape directing agents, and the performance of the catalyst was discussed. X-ray diffractometer (XRD), transmission electron microscope (TEM), inductively coupled plasma atomic emission spectrometry (ICP-AES) and scanning electron microscope (SEM) were used to microscopically characterize the synthesized catalyst, and the electrochemical workstation was used to analyze the electrochemical performance of synthesized catalyst. The results show that the Pt(100) crystal plane orientation catalyst added with KBr has the most regular cubic morphology and the most complete formation. At the same time, its electrocatalytic performance is the best. The electrochemically active surface area is 42.43 m(2)/g, the peak current density for ethanol oxidation is 417.67 A/g, and the steady-state current density value at 1100 s is 149.50 A/g. The activation energy of catalytic oxidation reaction for ethanol is the lowest of 24.76 kJ/mol, and the retention rate of the peak current density of ethanol oxidation is 82.26%.
