Abstract Herein, a robust microporous aluminum tetracarboxylate framework, MIL‐120(Al)‐AP, (MIL, AP: Institute Lavoisier and Ambient Pressure synthesis, respectively) is reported, which exhibits high CO 2 uptake (1.9 mmol g −1 at 0.1 bar, 298 K). In situ Synchrotron X‐ray diffraction measurements together with Monte Carlo simulations reveal that this structure offers favorable capture configuration the pores being decorated density of µ ‐OH groups accessible aromatic rings. Meanwhile, based on calculations experimental evidence, moderate host‐guest interactions Q st (CO ) value MIL‐120(Al)‐AP (−40 kJ mol deduced, suggesting relatively low energy penalty for full regeneration. Moreover, an environmentally friendly ambient pressure green route, relying inexpensive raw materials, developed to prepare kilogram scale yield while Metal‐ Organic Framework (MOF) further shaped inorganic binders as millimeter‐sized mechanically stable beads. First evidences its efficient /N separation ability are validated by breakthrough experiments operando IR indicate kinetically adsorption over water. Finally, techno‐economic analysis gives estimated production cost ≈ 13 $ kg , significantly lower than other benchmark MOFs. These advancements make excellent candidate adsorbent industrial‐scale processes.

The structural diversity and chemical functionality of metal–organic frameworks (MOFs) render them promising candidates for CO2 adsorption separation. However, their applications are often restricted by intrinsic fragility decreased processability. Herein, a hierarchical fibrous MOF/ionic liquid (IL) membrane was constructed assembling well-ordered ZIF-8 nanounits with an encapsulated IL along the polyimide (PI) fibers. This design promotes formation efficient three-dimensional gas transfer network generates abundance nanopores decorated CO2-philic units, thereby enhancing separation from N2. PI/ZIF-8/IL membranes exhibit remarkable features, including large specific surface area 79.89 m2 g–1, high porosity 93.28%, excellent mechanical stability. Moreover, demonstrate enhanced capacity 3.32 mmol/g at 298 K 1 bar, CO2/N2 selectivity 28, stable recyclable regeneration capability. integrated pore structure proposed in this study provides practical direction rational MOF/IL targeted applications.

Abstract To mitigate global climate change, the development of membranes with high CO 2 permeability and selectivity is urgently needed. Here, a simple effective non‐solvent‐induced microstructure rearrangement (MSR) technique proposed to enhance gas separation performance Pebax 2533 membranes. By immersing in amino acid salt solutions induce MSR, optimized 2533‐GlyK 10 wt.% membrane reached 1180 Barrer, 4.5‐fold increase compared original membrane, without compromising /N selectivity. Moreover, MSR maintains stable for nearly 500 days, demonstrating excellent long‐term stability. Furthermore, applying thin‐film composite (TFC) revealed that both 2533/polyvinyl chloride (PVC) hollow fiber (HF) TFC 2533/polyacrylonitrile (PAN) flat‐sheet exhibited significantly enhanced permeance under treatment DI water. Characterization results indicated chemical‐physical properties before after are unchanged, suggesting promising next‐generation carbon capture.
