| 摘 要： | 用化学沉积法制备炭载Pt(Pt/C)和以活性炭与石墨作混合载体的Pt(Pt/CG)催化剂。实验结果表明，活性炭与石墨质量比影响Pt/CG催化剂对乙醇氧化的电催化活性。当活性炭与石墨的质量比为15∶1时，制得的Pt/CG催化剂对乙醇氧化的电催化活性最高。

| Abstract: | The activated carbon supported Pt(Pt/C) and the mixture of the activated carbon and the graphite supported Pt(Pt/CG) catalysts were prepared using chemical reduction method. It was found that the weight ratio of the activated carbon and the graphite could affect the electrocatalytic activity of the Pt/CG catalysts for ethanol oxidation. When the weight ratio of the activated carbon and graphite is 15∶1, the Pt/CG catalyst shows the best electrocatalytic activity for ethanol oxidation. It is mainly attributed to the high dispersion of the precipitated Pt particles and the large electrochemically active area when the weight ratio of the activated carbon and the graphite is suitable. In addition, the addition of graphite would increase the conductivity of the catalyst. |
