MIL-53(Al) as a Versatile Platform for Ionic-Liquid/MOF Composites to Enhance CO₂ Selectivity over CH₄ and N₂.

ABSTRACT: Five different imidazolium-based ionic liquids (ILs) were incorporated into a metal-organic framework (MOF), MIL-53(Al), to investigate the effect of IL incorporation on the CO₂ separation performance of MIL-53(Al). CO₂ , CH₄ , and N₂ adsorption isotherms of the IL/MIL-53(Al) composites and pristine MIL-53(Al) were measured to evaluate the effect of the ILs on the CO₂ /CH₄ and CO₂ /N₂ selectivities of the MOF. Of the composite materials that were tested, [BMIM][PF₆ ]/MIL-53(Al) exhibited the largest increase in CO₂ /CH₄ selectivity, 2.8-times higher than that of pristine MIL-53(Al), whilst [BMIM][MeSO₄ ]/MIL-53(Al) exhibited the largest increase in CO₂
