Electrosynthesis of polyaniline in ionic liquid and its electrocatalytic properties

Abstract

Ionic liquid like 1-butyl-3-methyl- imidazolium tetrafluorobrate ([BMIM]BF4) has been used as solvent and electrolyte for the electropolymerization of aniline at glassy carbon electrode by cyclic voltammetry. Electrode modified with polyaniline (PAn) has obvious electrochemical activity in ionic liquid and acid solution (pH 0-4), and has significant electrocatalytic activity for redox reaction of catechol and hydroquione.
