Abstract

The binary composite ionic liquids mixtures composed of 1-hexyl-3-methylimidazolium tetrafluoroborate ([hmim][BF4]) and 1-hexyl-3-methylimidazolium hexafluorophosphate ([hmim][PF6]) were developed for reduction of nitrobenzene. ATR-IR spectroscopy was employed to achieve mixing behaviour of binary ionic liquids and significant change in the anion IR bands was observed. The electrochemical reduction of nitrobenzene was studied at platinum electrode in binary composite ionic liquids. Results indicated that the reduction reaction taken place in some binary composite ionic liquids demonstrated higher current densities with a more positive potential than in both single ionic liquids and the process was controlled by diffusion.
