性质:指一些电极反应的超电势与电流密度对数的线性关系式,即η=a+blgi,是塔菲尔于20世纪之初从氢超电势实验研究中总结得到的经验规律。对于不同的电极反应和同一反应不同的电极金属材料,常数α差别较大;而b值(即η-lgi图像中直线之斜率,称塔菲尔斜率)常较接近。对于汞、镉、锌、铅等氢超电势较高的金属,η约为-0.12V,对于铂、铑等氢超电势较低的金属,约为-0.03V。在20世纪20~30年代巴特勒-伏尔默公式提出后,知塔菲尔公式是该式在强极化区(|η|>0.1V)的简化形式,故也适用于其他迁越控制的电极反应;并明确了a和b的物理意义:对于迁越控制的电极反应,它们的比值反映了该反应的交换电流密度,即a/b=lgi0。
