“…Yang et al 117 investigated the effect of tetrabutylammonium bromide (TBAB)-based DESs on propylene carbonate (PC) in the cycloaddition reaction of CO 2 with propylene oxide (PO). This study showed that TBAB-TEA (1:1) is an efficient homogeneous catalyst for the cycloaddition reaction of CO 2 with epoxide, the yield of PC can reach up to 98% under the optimum reaction conditions, and the DESs show good recoverability.…”

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.
