Acidic ionic-liquids (IL) supported on metal-organic frameworks (MOFs) have been shown to be beneficial for adsorptive desulfurization. A remarkable improvement in the adsorption capacity (ca. 71%) was observed in for ILs supported on MIL-101 compared with virgin MIL-101. The improved adsorptive performance might be explained by the acid-base interactions between the acidic ionic liquid and basic benzothiophene (BT). Moreover, from this study, it can be suggested that porous MOFs, supported with ionic liquids, may introduce a new class of highly porous adsorbents for the efficient adsorption of various compounds.
酸性离子液体（IL）负载在金属-有机骨架（MOFs）上已被证明对吸附脱硫有益。与原始 MIL-101 相比，负载在 MIL-101 上的 IL 的吸附容量（约 71%）有显著提高。这种吸附性能的提高可以用酸性离子液体和碱性苯并噻吩（BT）之间的酸碱相互作用来解释。此外，从这项研究中可以推断，负载离子液体的多孔 MOFs 可能会为有效吸附各种化合物引入一类新的高多孔吸附剂。
