High cost and high energy penalty for CO uptake from flue gases are important obstacles in large-scale industrial applications, and developing efficient technology for CO capture from technical and economic points is crucial. Ionic liquids (ILs) show the potential for CO separation owing to their inherent advantages, and have been proposed as alternatives to overcome the drawbacks of conventional sorbents. Chemical modification of ILs to improve their performance in CO absorption has received more attention. Deep eutectic solvents (DESs) as a new generation of ILs are considered as more economical alternatives to cope with the deficiencies of high cost and high viscosity of conventional ILs. This Review discusses the potential of functionalized ILs and DESs as CO sorbents. Incorporation of CO -philic functional groups, such as amine, in cation and/or anion moiety of ILs can promot their absorption capacity. In general, the functionalization of the anion part of ILs is more effective than the cation part. DESs represent favorable solvent properties and are capable of capturing CO , but the research work is scarce and undeveloped compared to the studies conducted on ILs. It is possible to develop novel DESs with promising absorption capacity. However, more investigation needs to be carried out on the mechanism of CO sorption of DESs to clarify how these novel sorbents can be adjusted and fine-tuned to be best tailored as optimized media for CO capture.

“…The solubility of CO 2 in ChCl/glycerol (1:2) was investigated by Leron et al. The CO 2 solubility in these DESs was comparable with that of [C 4 MIM]‐based ILs (e.g., [C 4 MIM][PF 6 ] and [C 4 MIM][PF 6 ]), but higher than [C 2 MIM]‐based ILs (e.g., [C 2 MIM][BF 4 ] or [C 2 MIM][C 2 N 3 ]) …”

“…As shown in table 5, values of the solubility of CO 2 in the DESs studied are higher than those in the ammonium-based ILs [48], such as 2-hydroxy-N-(2-hydroxyethyl)-N-methylethanaminium lactate ([hhemel]) and 2-hydroxy-N-(2-hydroxyethyl)-Nmethylethanaminium acetate ([hhemea]), but slightly lower than those in the imidazolium ILs [49][50][51] . Moreover, values of the solubility of CO 2 in DESs are higher than those in dihydric alcohols (or lactic acid) and choline chloride [38,12], but lower than those in urea (or glycerol) and choline chloride [34,37,52]. These differences of the solubility demonstrate that the interactions between the groups in HBDs (with the exception of glycerol) and CO 2 follow the sequence of amide > carbonyl group > ether bond > hydroxyl group.…”

Deep eutectic solvents, as a new type of eco-friendly solvent, have attracted increasing attention in chemistry for the extraction and separation of target compounds from various samples. To summarize the application of deep eutectic solvents, this review highlights some of the unique properties of deep eutectic solvents and deep-eutectic-solvent-based materials, as well as their applications in extraction and separation. In this paper, the available data and references in this field are reviewed to summarize the application developments of deep eutectic solvents. Based on the development of deep eutectic solvents, the exploitation of new deep eutectic solvents and deep-eutectic-solvent-based materials are expected to diversify into extraction and separation.
