Electrochemical Behavior of 1, 4-Butanediol at Nickel Oxide-Polyaniline Composite Film

摘要

The composite film comprising nickel oxide dispersed in polyaniline was used to investigate the electro-oxidation of 1,4-butanediol in alkaline media. The composite film was electrochemically deposited using nickel sulphate and aniline solution. Surface coverage of the film in alkaline medium at different scan rates was indicated to involve a few hundred monolayers. Chronoamperometric and chronopotentiometric responses indicated that electro-oxidation of 1, 4-butanediol initiates from the very start of the anodic scan.
