| 摘 要： | 利用三角波电位扫描伏安法研究了铁电极在室温1mol/L KOH 溶液中的电化学行为。在正向扫描中产生3个阳极峰,分别对应于 Fe(OH)_2和 FeOOH的形成,它们在逆向扫描中顺序还原为 Fe(OH)_2和 Fe。温度对钝化过程有明显影响,交流阻抗谱证实了钝化膜的存在。

| Abstract: | The electrochemical behaviours of iron electrode in 1mol/E KOH sol- utions have been studied at ambient temperature by triangular potential sweep voltammetry.Three anodic peaks were detected in the anodic scan, forming Fe(OH)_2 and FeOOH respectively and they were subsequently reduced to Fe(OH)_2 and Fe in the cathodic scan.The great influence of temperature on the passive process has been observed Impedance spectrum showed that the film was existed in the passivated potential regions. |
