ABSTRACT
The world's population explosion creates a need for natural resources for energy, which will become a significant contributor to global climate change. As we all know, carbon dioxide (CO2) is one of the most critical elements of the global greenhouse gas effect. CO2 capture and storage innovations have piqued researchers' attention in recent decades. Compared to other methods, membrane separation has some positive performance in CO2 capture. CO2 capture with membrane separation using enhanced ionic liquids (ILs) is described in this review. ILs have made an appearance in CO2 capture work as the potential additive, and companies and academics have been interested in CO2 separation for the past two decades. This article comprehensively analyzes the current modern approach in ILs and IL-based membranes for gas separation processes. Based on the latest literature and performance data, this work provides a complete compressive examination of types of ILs and IL-supported membrane performances. ILs for CO2 capture were also explored, and IL-based membranes for different ILs were also studied. This study emphasizes the supremacy of novel ILs for CO2 capture in membrane separation.
