Abstract
Carbon capture and storage (CCS) technologies have gained global attention due to the environmental impact caused by CO2. Ionic liquid, also known as a designer solvent, has good potential for CO2 capture application due to its good CO2 affinity, negligible vapor pressure and high thermal stability. The combination of ionic liquid and membrane technology has been introduced for the more effective use of ionic liquid. This review offers a comprehensive overview of mixed matrix membrane (MMM) and the application of ionic liquid in the membrane for CO2 separation, focusing on recent advances in ionic liquid-based MMM. Descriptions of various MMM modification strategies using ionic liquid and the influence of challenging operating conditions on the CO2 separation performance of ionic liquid-based MMM are discussed.
