摘要

We report a supported liquid membrane (SLM) based on a task-specific ionic liquid to achieve the selective and facilitated CO₂ 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.
