摘要：

The development of advanced functional materials for efficient CO₂ capture, storage and conversion is crucial to mitigate climate change. Porous material like Metal organic frameworks (MOFs) and Zeolitic imidazolate frameworks (ZIFs), when combined with ionic liquids (ILs), promote selective CO₂ adsorption.^1-6 Employing DFT and GCMC simulations, we explored ILs impregnated MOFs and ZIFs to understand the structure property relationships influencing CO₂ affinity as well as selectivity under confinement. It is interesting to note that hydrophobic IL exhibits stronger CO₂ adsorption under confinement.⁵ This is due to the similar hydrophobicities (i.e. like-like pair) of ZIF-8 framework and the selected ILs. In addition, binary mixtures of hydrophobic IL@ZIF-8 promoted CO₂ selectivity up to 3.5-fold.³ UiO-66-based composites having aromatic cations ([BPy]⁺[BF₄]⁻) showed enhances 65% in CO₂/N₂ selectivity via π–π and van der Waals (vdWs) interactions, while aliphatic cations ([N₂₂₂₄]⁺) suffered from steric hindrance. Metal-based anions ([AlCl₄]⁻, [FeCl₄]⁻) further improved adsorption enthalpy and CO₂/CH₄ and CO₂/N₂ selectivity.⁶ Our studies provide molecular-level insights into IL framework synergy, driving the rational design of next-generation IL@MOF materials for CO₂ capture, storage, separation and catalytic conversion into other value-added products.
