| 摘 要： | 将电聚合的聚苯胺 (PAN)膜电极置于c(NiSO4 ) =2 5mol/L的溶液中浸泡 2 0min得到嵌入Ni2 的PAN Ni2 电极 ,该电极在KOH溶液中的循环伏安曲线于 0 30 7V/0 2 30V处有一对明显的氧化还原电流峰 ,表明Ni2 离子已嵌入PAN膜电极。PAN Ni2 电极对碱性介质中甲醇的氧化具有明显的电催化活性。

| Abstract: | PAN Ni 2 electrode was prepared using polyaniline film immersed in a solution of 2.5 mol/L NiSO-4 for about 20 minutes.The voltammetric behavior of the PAN Ni 2 electrode in alkaline aqueous solution showed that a couple of redox current peaks appeared at potentials of 0.307 V and 0.230 V,which indicated that Ni 2 has been embedded into the PAN film.The PAN Ni 2 film acted as an active substance for the electrocatalytic oxidation of methanol in alkaline solutions. |
