Abstract: Global warming due to the emission of greenhouse gases, especially carbon dioxide (CO2), has a significant effect on the climate change and has become a widespread concern in the recent years. Carbon capture, utilization, and sequestration (CCUS) strategy appears to be effective in decreasing the carbon dioxide level in the atmosphere. Despite a great progress in this field, there are still major limitations in commercialized the CO2 capture methods that rely on absorption phenomena. High capital costs of for the CO2 capture, low absorption and desorption rates (which require large facilities), solvent losses due to evaporation, and the use of corrosive solvents are among main obstructions. Recently, CO2 capture with ionic liquids (ILs) has appreciably attracted researchers’ attention. The distinct properties of ILs such as negligible vapor pressure and their affinity to capture the CO2 molecules make them a feasible alternative for currently available solvents including, different amines.
