A new Cd(II)-containing ionic liquid: Synthesis, characterization and electrocatalysis

Abstract

The present work reports on the synthesis, characterization and performance of a new metal-containing ionic liquid [(C 4H 9) 2-bta][(C 4H 9-bta)CdCl 3] (bta = benzotriazole) as electrocatalyst for hydrogen peroxide reduction. The structure of the Cd(II)-containing ionic liquid (Cd-IL) has been characterized by X-ray crystallography, IR spectroscopy and elemental analysis. The molecule contains one 1,3-dibutyl-benzotriazolium cation and an anionic Cd coordination entry. The electrochemical property of Cd-IL bulk-modified carbon paste electrode (Cd-IL/CPE) has been studied by cyclic voltammetry. The Cd-IL has functions both as a binder and an electrocatalyst. The Cd-IL/CPE shows good electrocatalytic activity towards the reduction of hydrogen peroxide. © Indian Academy of Sciences.
