“…1–7 Most MOF membranes for osmotic energy harvesting in previous studies were polycrystalline membranes which were fabricated by growing MOF crystals onto or into porous substrates, such as porous anodic aluminum oxide (AAO), polyethylene terephthalate (PET), and alumina nanochannel membranes (ANMs). For example, polycrystalline UiO-66-NH 2 , 8 ZIF-8, 9 ZnTCPP, 6 HKUST-1, 10 PSS/HKUST-1, 7 UiO-66-(COOH) 2 , 11 MOF-303, 12 spiropyrans/MIL-53, 13 PSS/MOF-199, 14 and ZIF Hep 15 have achieved osmotic energy generation with power densities ranging 1.46 W m −2 to 45.6 W m −2 under various electrolyte solutions. Polycrystalline MIL-53-COOH single nanochannel membranes have shown an estimated power density of 3174.3 W m −2 with a concentration gradient of 1000 under HCl solutions.…”

“…Moreover, studies on MOF-303 have been mainly dedicated to atmospheric water harvesting (AWH) [ 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ], and this MOF has been identified as one of the most efficient mediums for this application [ 21 ]. It quickly turned out that it is also a very good adsorbent for CO 2 [ 22 ], SO 2 [ 23 ], NH 3 [ 24 ], C 2 H 2 [ 25 ], Xe [ 26 ], alcohols [ 27 ], particulate matters [ 28 ], water contaminants [ 29 , 30 , 31 , 32 , 33 , 34 , 35 ], separation [ 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 ], and other applications [ 45 , 46 , 47 , 48 , 49 , 50 ]. For example, MOF-303 has a high CO 2 adsorption capacity of 5.1 mmol/g at 25 °C and under 1 bar, and what is equally important, the capacity was maintained after over 50 cycles of CO 2 adsorption and desorption experiments [ 22 ].…”

Metal–organic structures have great potential for practical applications in many areas. However, their widespread use is often hindered by time-consuming and expensive synthesis procedures that often involve hazardous solvents and, therefore, generate wastes that need to be remediated and/or recycled. The development of cleaner, safer, and more sustainable synthesis methods is extremely important and is needed in the context of green chemistry. In this work, a facile mechanochemical method involving water-assisted ball milling was used for the synthesis of MOF-303. The obtained MOF-303 exhibited a high specific surface area of 1180 m2/g and showed an excellent CO2 adsorption capacity of 9.5 mmol/g at 0 °C and under 1 bar.

Ion‐selective nanochannel membranes assembled from two‐dimensional (2D) nanosheets hold immense promise for power conversion using salinity gradient. However, they face challenges stemming from insufficient surface charge density, which impairs both permselectivity and durability. Herein, we present a novel vacancy‐engineered, oxygen‐deficient NiCo layered double hydroxide (NiCoLDH)/cellulose nanofibers‐wrapped carbon nanotubes (VOLDH/CNF‐CNT) composite membrane. This membrane, featuring abundant angstrom‐scale, cation‐selective nanochannels, is designed and fabricated through a synergistic combination of vacancy engineering and interfacial super‐assembly. The membrane shows interlayer free‐spacing of ~3.62 Å, which validates the membrane size exclusion selectivity.This strategy, validated by DFT calculations and experimental data, improves hydrophilicity and surface charge density, leading to the strong interaction with K+ ions to benefit the low ion transport resistance and exceptional charge selectivity. When employed in an artificial river water|seawater salinity gradient power generator, it delivers a high‐power density of 5.35 W/m2 with long‐term durability (20,000s), which is almost 400% higher than that of the pristine NiCoLDH membrane. Furthermore, it displays both pH‐ and temperature‐sensitive ion transport behavior, offering additional opportunities for optimization. This work establishes a basis for high‐performance salinity gradient power conversion and underscores the potential of vacancy engineering and super‐assembly in customizing 2D nanomaterials for diverse advanced nanofluidic energy devices.
