Summary: CO removal is an important topic, but the CO capture performance of reported absorbents is still unsatisfactory. In this study, a series of novel ionic liquids were developed for effective CO absorption and separation, showing excellent CO capture performance and reversible regeneration. The strategy of multi-copper sites provides important guidance for the design of solvents for CO selective separation and storage.

Summary: In this study, anion-functionalized deep eutectic solvents were synthesized for efficient SO2 capture, showing good reusability and reversibility. The high SO2 absorption capacity was attributed to the chemical reaction between SO2 and the anion, as well as the strong interaction between SO2 and the deep eutectic solvent.

Summary: We report a series of calculations on the mechanism of SO2 chemisorption in amino acid-based ionic liquids. The efficiency of chemical trapping of SO2 by the amino group of the amino acid is evaluated. It is found that SO2 is less reactive than CO2 and the specific amino acid side chain does not play a significant role. The bimolecular absorption processes for SO2 are unlikely to occur, which is different from CO2.

Summary: In this study, environmentally friendly and high-performance deep eutectic solvents were designed to simultaneously capture SO2 and NO2 from flue gas. The absorption performances and mechanisms were investigated using spectroscopy and simulations. The results showed that the solvents can absorb low concentrations of SO2 and NO2 simultaneously at low temperatures, and they exhibit outstanding regeneration capability.

Summary: Low-viscous homologue-paired liquids (HPLs) are special non-ionic deep eutectic solvents designed for selective separation of SO2 from CO2 and N-2. They exhibit excellent inherent properties, high absorption capacity, fast absorption rate, moderate interaction with SO2, good recyclability, and potential for industrial desulfurization applications.

Summary: CO2 emission is a global issue that needs to be addressed urgently. In order to achieve the carbon peaking and carbon neutrality goals in China, the development of CO2 capture technology is essential. Ionic liquids have been highly regarded in the field of CO2 capture and separation due to their unique properties such as low volatility, good gas solubility, and structure designability. This review focuses on the recent research progress in amino and non-amino functionalized ionic liquids, ionic liquid hybrid solvents, ionic liquid modified adsorbents, and membranes for CO2 capture and separation. The impacts of amino groups and electronegative functional sites on CO2 separation performance and mechanism, as well as the role of functionalized ionic liquids in hybrid solvents, adsorbents, and membranes, are summarized. The future development direction and prospects of ionic liquid-based CO2 capture technologies are also proposed.

Summary: A series of pyridinolate anion-functional ionic liquids with different cations were designed and studied for their SO2 absorption properties. The results showed that the interaction between cations and anions, as well as various structural parameters, have significant effects on the absorption of SO2. The mechanism of SO2 absorption was found to involve both physical and chemical adsorption processes.
