摘要/Abstract

摘要： 应用开路电位测量和循环伏安法研究碱性介质中Ｈ２ＰＯ－２在镍电极上的电氧化过程，并对镍氧化膜的去活化机理进行了探讨．结果表明，镍电极在碱性介质中由于氧化膜的快速形成而显示出明显的非催化活性．Ｈ２ＰＯ－２的氧化发生在较负的电位范围，ＨＰＯ２－３为氧化的最终产物．Ｈ２ＰＯ－２的氧化过程分为Ｈ２ＰＯ－２吸附、Ｐ－Ｈ键断裂、活性中间物形成及其氧化等步骤．Ｈ２ＰＯ－２与活性镍充分的相互作用是形成活性基团及随后氧化的必要条件．

Abstract: Electrooxidation of hypophosphite anions on polycrystalline nickel in alkaline solutions has been investigated by cyclic voltammetry and open circuit potential measurements.The results are explained based on the mechanism that the first step of hypophosphite oxidation is the adsorption of hypophosphite ions on nickel,followed by the homolysis of its hydrogen bond with the formation of radicals.The oxidation of hypophosphite on nickel in alkaline medium occurs at lower potentials between ca.-0.8 V—-1.1 V(SCE)and phosphite ion is the only oxidation product.There is no indication of hypophosphite oxidation at higher potentials.Severe deactivation of the surface occurs when the nickel surface is covered with surface oxide/hydroxide films which separates the hypophosphite ion from nickel substrate.The results show that the rate of the anodic oxidation of hypophosphite depends strongly on the nature of the nickel substrate,operation temperature,hypophosphite concentration and sweep rate.
