Abstract: 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.

Key words: The stearate nickel L B film, Electrocatalytic oxidation methanol
