Ionic liquids display good CO2 absorption capacity but poor absorption kinetics and high costs. In the present work, we show that these problems can be solved by impregnating the new low-cost ionic liquid pentaethylenehexammonium chloride [PEHA][Cl] and the corresponding amine precursor on a low-cost mesoporous microsphere support. The results showed that sorbents displayed excellent sorption kinetics and capacity, comparable to the best reports in...
