Abstract

The enormous emission of carbon dioxide (CO2) from industries has triggered a series of environmental issues. In recent years, ionic liquids (ILs) as novel absorbents are widely used for CO2 capture owing to their low vapor pressure and tunable structures. IL‐modified adsorbents have the advantages of both ILs and porous supports, such as high CO2 selectivity and high specific surface area, which are novel agents to capture CO2 with broad application prospects. In this review, more than 140 IL‐modified adsorbents for CO2 capture in recent years were systematically summarized. The types of ILs including conventional ILs and functionalized ILs on CO2 separation performance of different IL hybrid adsorbents, and their adsorption mechanisms were also discussed. Finally, future perspectives on IL‐modified adsorbents for CO2 separation were further posed.
