“…We can also highlight that the higher the ILs content the lower these values were probably due to pore filling. These data corroborates several studies reporting textural properties decrease after organic loading 2,[49][50][51] and also confirm that the relationship between bulk density and porosity is inversely proportional 54 . /g).…”

Ionic liquids (ILs) physical immobilization in solid materials is a key strategy for developing efficient and low cost CO 2 capture processes. In this work, two porous commercial substrates with different characteristics (silica and alumina) were impregnated with ILs by physical wet method. Imidazolium based IL combined with [Br]and [Tf 2 N]anions were used in impregnation process. CO 2 sorption capacity and selectivity (CO 2 /N 2) of these materials were investigated. The best results regarding CO 2 /N 2 selectivity and CO 2 sorption were obtained with [Tf 2 N]anion. In relation to solid support, commercial alumina exhibited enhanced CO 2 uptake and higher selective capacity (CO 2 /N 2) (6.1 (± 0.1)). Combination of commercial alumina as support and 20 wt% of mbmim [Tf 2 N] resulted in higher CO 2 /N 2 selectivity of 9.5 ± 1.0. In addition, this material also showed fast sorption kinetics when compared to pure IL besides reuse capacity.

“…For the supported IL adsorbents, ILs can be impregnated into different supports and the synthesis method is convenient, so supported IL adsorbents are extensively studied in CO 2 separation. [92][93][94][95][96][97][98][99][100] However, due to the block of the pore structure in the supports during the synthesis process and easy loss of ILs, the reusability needed to be improved in future work. and so on.…”

The enormous emission of carbon dioxide (CO 2 ) from industries has triggered a series of environmental issues. In recent years, ionic liquids (ILs) as novel absorbents are widely used for CO 2 capture owing to their low vapor pressure and tunable structures. IL-modified adsorbents have the advantages of both ILs and porous supports, such as high CO 2 selectivity and high specific surface area, which are novel agents to capture CO 2 with broad application prospects. In this review, more than 140 IL-modified adsorbents for CO 2 capture in recent years were systematically summarized. The types of ILs including conventional ILs and functionalized ILs on CO 2 separation performance of different IL hybrid adsorbents, and their adsorption mechanisms were also discussed. Finally, future perspectives on IL-modified adsorbents for CO 2 separation were further posed.

“…The results showed that the pore expansion of a support can improve the CO 2 adsorption performances of the AAIL-loaded sorbents. Balsamo et al [19] prepared the supported ionic liquid adsorbent via wet impregnation of a mesoporous γ-Al 2 O 3 with [emim][Gly] at different loading. The preliminary experiment of cyclic adsorption/desorption showed that the capacity of CO 2 capture was strong.…”
