摘　　要：硬脂酸镍Ｌ－Ｂ膜电极对甲醇具有良好的电催化作用．膜中镍离子主要以－ＣＯＯＮｉ（ＯＨ）形式存在．电催化过程受ＯＨ－浓度的影响，也涉及甲醇分子在膜内的穿透．The stearate nickel L B films is good electroacatlyst for the oxidation of methanol MeOH in alkaline. The electrochemical behaviors of stearate nickel L B films is affected by the concentration of KOH. The rate of quantity of mickel ion and stearic acid in L B films is 1∶1, which means that the nickel ion may exist in -COONi(OH) form. The electrocatalytic process is influenced by the concentration of OH - , it involves the penetration of MeOH into the films. The oxidative currents of MeOH are linearly dependent on the bulk concentration.
