“…The research indicated that TETA-carbamate could decompose at 90 °C and cycle multiple times without significant performance degradation, demonstrating good cycling performance and relatively stable absorption properties of the solvent. Wang et al have developed an efficient biphasic solvent (DETA-EG-PMDETA) for CO 2 absorption. The solvent exhibits a CO 2 saturation capacity of up to 2.02 mol/mol, with a CO 2 loading in the rich CO 2 phase reaching 6.01 mol/L.…”

With global warming, more and more environmental problems have begun to appear, and people have gradually come to realize that the reckless emission of greenhouse gases will lead to a drastic deterioration to the ecological environment. In order to solve the environmental problems caused by global warming, more and more scientists have begun to work on improving the current situation of greenhouse gases emissions. CO 2 is a greenhouse gas that can be found everywhere in our daily life, and its contribution to the total greenhouse gas accounts for about 50%. Furthermore, the concentration of CO 2 is increasing with the advancement of human society. The main reason for the growth of CO 2 concentrations in the atmosphere is the extensive use of fossil fuels. Therefore, it is necessary to absorb CO 2 from industrial emissions. Many CO 2 capture methods have been proposed. As the research progressed, scientists found that deep eutectic solvents (DESs) show a bright future for CO 2 capture due to their advantages like high CO 2 absorption capacity, good solvent renewability, low price, less pollution, etc. Many articles have reported the absorption of CO 2 using DESs and in situ conversion of absorbed CO 2 . This article reviews the progress of DESs in absorbing CO 2 . DESs as absorbents for CO 2 absorption are discussed following the aspects of quaternary-ammonium-salt-based DESs, azole-based DESs, amine-and amino-acidbased DESs, ionic-liquid-based DESs, ternary DESs, and other types of DESs for absorbing CO 2 . DESs cooperate with other methods to absorb CO 2 . Lastly, in situ conversions of CO 2 in DESs are also discussed for regenerating DESs for energy saving. This article discusses general trends in the development of DESs for CO 2 capture and evaluates the challenging aspects of DESs for CO 2 absorption.

Ionic liquid (IL) can not only serve as solvents to reduce carbon capture energy consumption, but also may activate the CO2 absorption of amine solutions. Here, the absorption mechanism and kinetic modeling of IL‐activated single and mixed amines were studied in wetted wall column. N‐(2‐aminoethyl) ethanolamine (AEEA) and N,N‐diethylethanolamine (DEEA) were used as representatives to evaluate the IL activation effects on primary and tertiary amines. It was found that IL activated the reaction process of primary amine, but had no activation effect on tertiary amine. The activation energy of AEEA‐IL‐CO2 was 22.2 kJ/mol, which was 21.0% lower than AEEA‐CO2. Kinetic modeling of IL‐activated AEEA and mixed amines was established. Besides, the density functional theory calculations showed that IL can form hydrogen bonding and other interactions with AEEA and CO2 to activate the absorption reaction, which can reduce 29.3% activation energy during the zwitterion formation stage.
