| 摘 要： | 研究了乙醇在碱性介质（１．０ｍｏｌ．Ｌ＾－１ＮａＯＨ）中电沉积制备的Ｐｂ／ＧＣ、Ｐｔ／ＧＣ和Ｐｄ－ｐｔ／ＧＣ电极上的电催化氧化，实验结果表明：由此法制备的钯铂系列合金电极对乙醇的电催化氧化表现出明显的协同效应－乙醇的含钯原子分数ｙｐｄ＝０．３３６的ｐｄ－ｐｔ／ＧＣ合金电极上的节极交换电流密度是其在纯铂电极上的３０多倍。

| Abstract: | The electrocatalytic oxidation of ethanol on Pd/GC, Pt/GC and Pd-Pt/GC alloy electrodes prepared by electrodeposition was studied in alkaline medium (1. 0 mol•L-1 NaOH). The experimental results show that a synergism was observed on Pd-Pt/GC alloy electrodes for the electrocatalytic oxidation of ethanol--yPd =0. 336 Pd-Pt/GC alloy electrode demonstrates the highest activity, the corresponding exchange current density is more than 30 times greater than that on Pure Pt/GC electrode. |
