摘要 制备了Pt ZrO2/C催化剂,采用TEM,XRD等技术对其进行表征.利用循环伏安和电化学阻抗谱等方法研究Pt ZrO2/C催化剂在碱性溶液中对乙醇氧化的电化学活性,并与Pt/C催化剂(20%Pt,E TEK)进行对比.研究结果表明,Pt ZrO2/C催化剂具有较高的乙醇电氧化催化活性.电流密度最高的是n(Pt)∶n(ZrO2)为1∶1的样品,该比值为1∶4时显示出最低乙醇氧化峰电势. Pt- ZrO2/C catalyst was prepared and characterized by TEM and XRD. The electrochemical activity of Pt- ZrO2/C catalyst for ethanol oxidation was investigated by using cyclic voltammetry and electrochemical impedance spectroscopy in alkaline solutions and compared with Pt/C （20 % Pt, E-TEK）. The results showed that Pt- ZrO2/C gave higher catalytic activity for ethanol electro-oxidation. The highest current density was obtained at Pt/ZrO2 molar ratio with 1 ： 1 and the lower peak potential appeared when the Pt/ZrO2 molar ratio was 1：4.
