Creating structural defects in a controlled manner within metal–organic frameworks (MOFs) poses significant challenge for synthesis, and concurrently, identifying the types distributions of these is also formidable task characterization. In this study, we demonstrate that by employing 2-sulfonylterephthalic acid as ligand synthesizing Zr (or Hf)-based MOFs, crystal phase transformation from common fcu topology to rare jmt can be easily facilitated using straightforward mixed-solvent strategy. The phase, characterized an extensively open framework, considered derivative generated through introduction missing-cluster defects. We have explicitly identified both MOF phases, their intermediate states, novel core–shell structures they form ultralow-dose high-resolution transmission electron microscopy. addition facilitating engineering, incorporation sulfonic groups MOFs imparts ionic selectivity, making them applicable osmotic energy harvesting mixed matrix membrane fabrication. containing jmt-phase exhibits exceptionally high peak power density 10.08 W m–2 under 50-fold salinity gradient (NaCl: 0.5 M|0.01 M), which surpasses threshold 5 commercial applications attributed combination large pore size, extensive porosity, abundant material.

Electronic grade hydrogen peroxide plays a crucial role in the fabrication of large-scale integrated circuits. However, prepared by anthraquinone method contains impurities such as lead ions (Pb2+) and phosphate, which can seriously affect yield circuit. Traditional adsorbent materials have difficulty solving problem simultaneous adsorption trace anions cations due to single site poor kinetics. In this study, UiO-66-NH2 was introducing -NH2 group on terephthalic acid ligand, series hybrid matrix hollow fiber membranes with different contents were loading it polysulfone (PSF). This initiative not only improved pore size water flux but also enhanced removal efficiency from solution, thereby facilitating practical application. Among them, [email protected] showed best phosphate capacities 3.099 2.160 mg g-1 reached 67.1 60.1%, fully confirms practicability purification electronic chemicals. work innovatively proposes that UiO-66-NH2@PSF great potential adsorbents for efficient solvents.

Probing Structural Imperfections: Protein-Aided Defect Characterization in Metal–Organic Frameworks

ACS Materials Letters, Год журнала: 2024, Номер 6(4), С. 1396 - 1403

Опубликована: Март 11, 2024

Defect engineering proves to be a highly effective approach for introducing additional open metal sites and porosity into metal–organic frameworks (MOFs), thereby enhancing their gas storage, separation, chemical catalysis capabilities. However, characterizing defective MOFs, which often exhibit nonuniform pores, presents significant challenge. While probe molecules have been widely utilized explore the physical properties of MOF application has predominantly limited gas- or vapor-phase molecules. In this study, we present novel by employing size-selective fluorescent protein characterize macroporous defects induced tartaric acid in zirconium-based MOF, NU-1000. The spatial visualization using hemoglobin-based allows identification distinct structural weak points defect formation mechanisms NU-1000 crystallites prepared various methods. addition confirming findings from conventional characterization methods, such as sorption isotherms powdered X-ray diffraction analysis, unveils nuances overlooked many traditional techniques.
