Two task-specific ionic liquids (TSILs) were encapsulated into the framework of a Zeolite imidazolate framework-8 (ZIF-8) to enhance its CO₂ capture capacity and CO₂/N₂ selectivity at post-combustion conditions. 1-Ethyl-3-methylimidazolium amino-acetate {[EMIM][glycine (Gly)]} and 1-Ethyl-3-methylimidazolium (S)-2-aminopropionate {[EMIM][alanine (Ala)]} were selected as TSILs. TSIL@ZIF-8 composite sorbents were prepared by varying the loading of TSIL, and properties such as sorbent thermal stability, porous structure and crystal nature of the composite were investigated. The incorporation of TSIL into ZIF-8 led to a dramatic rise in CO₂ uptake particularly at pressures lower than 1.0 bar. At this low-pressure range, CO₂ uptake was greater than in pristine ZIF-8 for all TSIL loadings and TSIL@ZIF-8 composites with 30 wt.% [Emim][Gly] reached a CO₂ uptake capacity of 0.76 mmol·g^-1 solid at 0.1 bar, and 0.88 mmol/g-solid at 0.2 bar at 303 K. These values were 13 and 7 times higher that CO₂ uptake in pristine ZIF-8 at identical conditions. TSIL functionalized composites also exhibited much higher selectivity than pristine ZIF-8 at all pressures. For instance, at 30 wt.% [EMIM][Gly] loading, CO₂/N₂ ideal selectivities at 313 K were 28 and 19 at 0.1 and 0.2 bar, respectively. This synthesized composite sorbent, with significantly high CO₂ uptake, better CO₂/N₂ selectivity at the low-pressure region (<1.0 bar), and low isosteric heat of adsorption (Q_st), confirms that TSIL@ZIF-8 composites can be potential candidates for post-combustion CO₂ capture processes and opens the door for the further development of suitable TSIL@MOF composite sorbent to be deployed in the CO₂ capture process.
