Abstract

A strategy to improve SO₂ capture through tuning the electronegativity of the interaction site in ILs has been presented. Two types of imidazolium ionic liquids that include less electronegative sulfur or carbon sites were used for the capture of SO₂, which exhibit extremely highly available capacity, rapid absorption rate and excellent reversibility.
