| 摘 要： | 利用循环伏安法制备了Pt-Ru/GC电极并用于对甲醇的电催化氧化研究,考察了Pt、Ru原子比、沉积电位下限和沉积量对电极催化性能的影响,研究了电极催化性能的稳定性。结果表明Ru的加入对电极催化性能具有明显的改善作用,对甲醇的氧化电位范围明显变宽,氧化电流明显增大,电极的稳定性明显高于Pt/GC电极。在Pt、Ru原子比为1:1、沉积电位下限为-0.2V、沉积量为40r的条件下,Pt-Ru/GC电极对甲醇电催化氧化的性能最好。

| Abstract: | Pt-Ru/GC electrode was prepared by cyclic voltammetric method and was used to study the electrocatalytic oxidization of methanol.The effects of different Pt and Ru atomic number ratio,lower depositional potential and cyclic times of the electrode on catalytic properties were investigated.The stability of catalytic property was studied.The results show that the catalytic properties of electrode was improved obviously when Ru was added.The oxidative potential scope of methanol was broadened considerably.The oxidation current of methanol was increased obviously.The stability of Pt-Ru/GC electrode was obviously higher than Pt/GC electrode’s.The best deposited conditions of Pt-Ru/GC electrode were that Pt,Ru atomic number ratio was 1∶1,lower depositional potential was-0.2V and the cyclic times were 40r. |
