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.　Copyright　©　2022　Foorginezhad,　Yu　and　Ji.
