|a A decrease in CO2 emissions is urgently required in the present situation due to the fast growth of carbon dioxide (CO2) in the atmosphere, which has caused a series of global climate issues. This study used an impregnation-evaporation method to immobilize an amino functionalized ionic liquid [C2OHmim][Lys] on a chromatographic column filler GDX-103 and create a novel supported ionic liquid. The results showed that the supported ionic liquid with 60 wt % ionic liquid content had the best adsorption performance at 40 °C, and the CO2 adsorption isotherm showed that the adsorption capacity at 0.1 MPa was 1.29 mmol CO2/g sorbent, which was 6 times greater than the adsorption capacity of the pure carrier. The sample with 60% ionic liquid content has an adsorption capacity of 1.02 mmol CO2/g sorbent under the condition of CO2/N2 mixed gas with 10% CO2 content. This is 43 times greater than the adsorption capacity of the pure carrier, and its adsorption performance is stable after three adsorption and desorption cycles. Through the rich porous structure of GDX-103, the ionic liquid is effectively supported and dispersed, which expands the contact area between CO2 and ionic liquid and enhances the mass transfer of CO2. At the same time, CO2 can be chemically bound to the groups on the anion of ionic liquid and be immobilized, so it has a high selective adsorption capacity of CO2, which makes it a great alternative to traditional CO2 adsorbents
