甘油和乙醇在Pt-CeO2/C电极上的氧化
Oxidation of glycerol and ethanol on Pt-CeO2/C electrodes
【摘要】 用交替微波加热法快速制备CeO2 /C复合材料 ,进而制备Pt CeO2 /C。用电化学方法研究了甘油、乙醇在KOH溶液中 ,在Pt/C和Pt CeO2 /C电极上的电化学氧化性能。结果显示 :负载在碳粉上的Pt和Pt CeO2 催化剂对甘油和乙醇的电化学氧化具有较高的活性 ,而Pt CeO2 /C催化剂与Pt/C催化剂相比 ,表现了更好的活性和更强的抗毒化能力
【Abstract】 CeO2/C composite was prepared by intermittent microwave heating (IMH) method and used as support to make Pt-CeO2/C catalyst. The electrochemical oxidation properties of glycerol and ethanol on Pt/C or Pt-CeO2/C electrodes were measured by electrochemical techniques. The results showed that both Pt/C and Pt-CeO2/C electrodes were active for the oxidation of glycerol and ethanol.Pt-CeO2/C catalyst had better activity and poisoning resistance than that of Pt/C.
