1. A method for catalyzing both CO2 sorption and desorption in chemisorption; comprising:
providing an ionic liquid catalyst, wherein the ionic liquid catalyst is configured to capture CO2 and the ionic liquid catalyst is produced from a reaction between a catalytic amine and an ionic liquid, wherein an ester group of the ionic liquid reacts with the catalytic amine to produce the ionic catalyst;
providing CO2 through a gas inlet; and
absorbing and desorbing the CO2.
