The emergence of ionic liquids (ILs) has provided a highly effective and energy-saving way for separation and recovery of NH₃ owing to their remarkable advantages, such as very low volatility and structure designability. This review presents a comprehensive summary on the latest progresses of pure ILs, IL hybrid solvents, and IL composite materials for NH₃ separation from the perspective of material design to process simulation, involving the role of anions, cations, and functional sites of ILs in NH₃ separation performance of IL-based systems, the interaction mechanisms between ILs and NH₃, as well as the simulation of IL-based NH₃ separation process. Finally, the research challenges and perspectives of IL-based NH₃ separation and recovery in future are discussed.
