Electro-oxidation of ethanol on highly preferred orientation nickel electrode in NaOH

摘要

The electro-oxidation of ethanol on a highly preferred orientation (220) Ni electrode and a lower texture degree Ni electrode in 1 mol/L NaoH was investigated with cyclic voltammetry. The mechanism of ethanol oxidation on the highly preferred orientation Ni electrode is proposed. It is shown that the current peak of electro-oxidation of ethanol on the highly preferred orientation (220) Ni electrode is much higher than that of the lower texture degree (220) Ni electrode, Ni(III) on the surface of the highly preferred orientation(220)Ni electrode is responsible for the oxidation of ethanol.
