Ionic liquid-formulated hybrid solvents for CO2 capture

Ionic liquids are believed to be a class of green solvents with potential applications in the post-combustion capture of CO2. However, some inherent defects of ionic liquids, such as high cost and viscosity, significantly limit their industrial applications. Integrating ionic liquids with other materials represents a promising strategy to adjust the physical properties of ionic liquids and promote their real applications in industry. In this mini review, the progress to date in the fabrication of hybrid solvents based on ionic liquids for CO2 capture was described. The advantages and disadvantages associated with these hybrid solvents were discussed. Future directions and prospects for CO2 capture with ionic liquids were also outlined.
