| 中文摘要: |
| 通过交流伏安法,发现碱性体系中镍电极在很负的电位下有非常规的法拉第电流响应。根据金属水合氧化物催化理论,电流响应是由镍表面缺陷处原子氧化成镍的水合氧化物引起的,由于其起始电位与次亚磷酸根氧化的起始电位相同,所以认为镍的水合氧化物是催化次亚磷酸根氧化的真正物种。 |
| 英文摘要: |
| Faradic responses of nickel electrode were detected in rather negative potential region by AC voltammetry in basic solution. Based on the incipient hydrous oxide adatom mediator model, the oxidation of nickel atoms at the defects to nickel hydrous oxide lead to the Faradic responses. Hypophosphite oxidation and the formation of nickel hydrous oxide began at the same potential, so nickel hydrous oxide may play the role of catalyst for hypophosphite oxidation. |
