“…The synergistic effect offered by confined IL and ZIF-8 nanocages led to a significant increase in CO 2 capacity and selectivity, far exceeding the individual IL or ZIF-8. Recently, our group reported the in situ construction of ionic ultramicroporous metal–organic frameworks (IU-MOFs) using Cu-BTC and ionic liquids (PO-IL) (Figure b) . The 1-aminoethyl-3-methylimidazolium phenoxylate served as the competitive ligands of MOFs through the coordination of −NH 2 and Cu 2+ .…”

“…Recently, our group reported the in situ construction of ionic ultramicroporous metal−organic frameworks (IU-MOFs) using Cu-BTC and ionic liquids (PO-IL) (Figure 1b). 64 The 1-aminoethyl-3-methylimidazolium phenoxylate served as the competitive ligands of MOFs through the coordination of −NH 2 and Cu 2+ . The aromatic counterion, adorned with an oxygen-containing functional group side chain, served as the basic site promoting the interaction with CO 2 .…”

Pore engineering of metal–organic frameworks for boosting low-pressure CO2 capture

“…Lately, a one-step in situ coordination strategy was developed to construct several ionic ultramicroporous MOFs for efficient CO 2 capture. 128 Among these phenoxylate anionfunctionalized ionic liquid modied MOFs, Cu-PO-1 exhibits the highest CO 2 adsorption capacity (6.65 mmol g −1 ) at 298 K and 1 bar, far surpassing that of bulk HKUST-1 (3.30 mmol g −1 ). Molecular simulations revealed that the oxygen anions from phenoxy enhanced the framework polarity, enabling the improvement of Cu-PO-1's affinity with CO 2 .…”

Enhanced CO oxidation in porous metal-oxide nanoparticles derived from MOFs

“…27,28 In addition, the preparation methods of MOFs are simple and diverse, such as hydrothermal, microwave, ionic liquid and stencil methods. 29–32 It has been reported that metal oxide nanoparticles produced using MOFs can be well applied in the adsorption and battery fields. 33,34 However, there are few reports on the application of porous metal oxide nanoparticles in catalysis.…”
