Cross-linked, porous imidazolium-based poly(ionic liquid)s for CO₂ capture and utilisation

Abstract

CO2 is the most influential greenhouse gas with its drastic effects all over the world. Meanwhile, global warming is considered as a hot topic to different slices of scientists dealing...

The AEROPILs Generation: Novel Poly(Ionic Liquid)-Based Aerogels for CO2 Capture

“…Among the several AEROPILs, the largest CO 2 adsorbed amount obtained after exposure to CO 2 for 10 min was 0.70 mmol g −1 (CHT:P[DADMA]Cl 30% -Table 4, entry 6), which corresponds to 35-fold higher than pure chitosan (0.02 mmol g −1 ) [30]. Comparing with other porous PILs, for example the ones described by Eftaiha et al (0.59 mmol g −1 at 25 • C and 1 bar) [51], our material poses a promising CO 2 sorption capacity. Additionally, the amount of PIL (maximum of 30% w/w with respect to chitosan) used on AEROPILs was lower than for the materials described by Esko et al (IL or ionogel content between 40-80 wt%) [36] and Ding et al (80 wt% COF-IL) [35].…”

A Review on SAPO‐34 Zeolite Materials for CO2 Capture and Conversion

“…Finally, the materials of the adsorbents must be economically viable and readily available. [103] Numerous adsorbents have been reported for CO 2 capture, including zeolites, [93,95,104] ceramics, [105,106] carbonates, [107,108] metal and metal oxides, [24,25] carbonaceous materials, [100,109,110] amines, hydroxides, [111,112] polymers, [113,114] ionic liquids, [115] covalent organic frameworks, [116] and metal-organic frameworks (MOFs). [117][118][119][120][121][122][123][124][125][126][127] Acid-base neutralization reactions also play a key role in capturing CO 2 .…”

CO2 fixation into cyclic carbonates catalyzed by single-site aprotic organocatalysts

“…70 This attracted the attention of our research group and the CO 2 community to explore the utility of these compounds experimentally and theoretically. 31,71 Our research highlighted that the imidazolium family was not limited to synthetic polymers or biomaterial-based organocatalysts, 72,73 but this work could also be expanded into the use of IL precursors and their polymeric counterparts. Herein, a series of mono- and bi-functionalized homogeneous catalysts together with a heterogeneous imidazolium-based catalyst were synthesized and utilized for the cycloaddition reaction to yield CCs.…”
