Toward rational design of ionic liquid/metal-organic framework composites: effects of interionic interaction energy

Abstract

One of the structural factors controlling the extent of interactions between ionic liquids (ILs) and metal-organic frameworks (MOFs) in IL/MOF composites is elucidated. Results showed that the thermal stability limits and adsorption performances of the IL/MOF composites can be tuned by the interionic interaction energy of bulk ILs, which can be probed spectroscopically via C2H infrared stretching frequency.
