We report a supported liquid membrane (SLM) based on a task-specific ionic liquid to achieve the selective and facilitated CO, transport through the membrane. The prepared SLM facilitated by the amine-terminated ionic liquid showed high selectivity and high stability (more than 260 days) for CO2 separation from the CO2/CH4 gas mixture.
