CO2 capture is essential for both mitigating CO2 emissions and purifying/conditioning gases for fuel and chemical production. To further improve the process performance with low environmental impacts, different strategies have been proposed, where developing liquid green absorbent for capturing CO2 is one of the effective options. Ionic liquids (IL)/deep eutectic solvents (DES) have recently emerged as green absorbents with unique properties, especially DESs also benefit from facile synthesis, low toxicity, and high biodegradability. To promote their development, this work summarized the recent research progress on ILs/DESs developed for CO2 capture from the aspects of those physical- and chemical-based, and COSMO-RS was combined to predict the properties that are unavailable from published articles in order to evaluate their performance based on the key properties for different IL/DES-based technologies. Finally, top 10 ILs/DESs were listed based on the corresponding criteria. The shared information will provide insight into screening and further developing IL/DES-based technologies for CO2 capture.

“…The functionalized DESs can chemically capture CO 2 and hold great promise for post-combustion capture. Interested readers can refer to anion-functionalized DESs like azolide-based DESs [14], superbase-based DESs like the mixture of biophenol-derived superbase ILs and ethylene glycol [15] and hydrophobic polyamine-based DESs [16].…”

“…It should be noted that many functionalized DESs can chemically capture CO 2 and hold great promise for postcombustion capture. Interested readers can refer to anion-functionalized DESs like azolide-based DESs., superbase-based DESs like the mixture of biophenol-derived superbase ILs and ethylene glycol, and hydrophobic polyamine-based DESs . The group contribution method (GCM) and the conductor-like screening model for real solvents (COSMO-RS) are recommended for the prediction of several of the important thermodynamic properties of solvents .…”

Hydrophobic deep eutectic solvents (DESs) have been designed as effective solvents for precombustion CO2 capture by using a conductor-like screening model for real solvents (COSMO-RS). Reliable CO2 solubilities in various compounds and binary solvents were estimated. We have developed new DESs from 38 selected, nature-derived, hydrophobic, and CO2 affinitive compounds. The possibilities of any two of these substances to form DESs were assessed from predicted activity coefficients, followed by an estimation of the CO2 solubilities of the theoretically feasible DESs. 58 promising hypothetical DESs were screened out. Subsequently, eight DESs were successfully prepared and characterized. Most of these DESs have a density larger than 1.0 g/mL at 298.15 K. The DESs have a similarly low volatility as decanoic acid–menthol (1:2) and are thermally stable below 420 K. Vanillin-4-oxoisophorone (1:3) and methyl salicylate-4-oxoisophorone (1:1) have been identified to be very promising for precombustion capture, showing comparable CO2 solubility and viscosity to the well-known, conventionally used Selexol solvent.
