“…Combining ionic liquids with organic or inorganic porous materials by physical or chemical methods to form supported ionic liquid materials as CO 2 adsorbents, which share the benefits of both ionic liquids and porous materials, can not only improve the selective separation effect but also successfully avoid the high viscosity caused by the direct absorption of CO 2 by ionic liquids and improve the CO 2 adsorption efficiency.

A decrease in CO 2 emissions is urgently required in the present situation due to the fast growth of carbon dioxide (CO 2 ) 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 [C 2 OHmim][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 CO 2 adsorption isotherm showed that the adsorption capacity at 0.1 MPa was 1.29 mmol CO 2 /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 CO 2 /g sorbent under the condition of CO 2 /N 2 mixed gas with 10% CO 2 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 CO 2 and ionic liquid and enhances the mass transfer of CO 2 . At the same time, CO 2 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 CO 2 , which makes it a great alternative to traditional CO 2 adsorbents.

Amino acid ionic liquids (AAILs) exhibit prominent merits for CO2 capture including biocompatibility and good stability, but they still suffer from several demerits, such as high viscosity and low molecular utilization. Therefore, it is critical to construct proper systems that can address these problems to enhance CO2 absorption of AAILs. In this work, three types of AAIL absorbent systems, DMEE (2-[2-(dimethylamino) ethoxy] ethanol)–AAIL, H2O–AAIL, and EG (ethylene glycol)–AAIL, are prepared with six AAILs that have different amino acids. The absorption performance of these absorbents is characterized to investigate the reinforcing effects of the additives on the absorption properties of AAILs. With temperatures ranging from 293 to 313 K, the CO2 capture studies on the binary systems reveal that AAILs present better absorption efficiency when their concentrations are 40 or 50 wt %. Based on the zwitterion reaction mechanism model and a thermodynamic model, the interactions of AAILs with H2O, DMEE, and EG systems for absorbing CO2 are discussed, respectively. The results obtained in this work indicate that AAIL–DMEE systems are promising candidates for CO2 capture since the interaction between AAILs and DMEE increases the capacity of AAILs and promotes kinetics.
