“…Other phenomena such as adsorption and surface diffusion are also relevant and dependent on pore size (SADRZADEH; MOHAMMADI, 2019; SADRZADEH; REZAKAZEMI; MOHAMMADI, 2018). Knudsen diffusion was prominent in only a few studies, none of which dealt with polymeric membranes and mostly focused on MOF types (AL-MAYTHALONY et al, 2015;FENG et al, 2020;JIANG et al, 2021;KANEZASHI;LIN, 2009;LEE et al, 2012;LI et al, 2021;LIAN et al, 2022;LIU et al, 2009;PENG et al, 2017;WU et al, 2022).…”

The countless possibilities associated with the design of new materials for the Membrane Gas Separation Process highlight the need for the creation of databases, that are great tools to guide design choices. The scientific literature is poor in providing detailed information on gas separation membranes. This work aimed to present a heterogeneous and detailed database, which encompasses various types of membranes and permeating gases. In addition, its construction was presented in a transparent manner (ensuring its suitability and safe use) and an analysis of the mined attributes was performed. A database with 1672 records was built with more than 280 different membranes. In total, 29 attributes were collected from 42 different bibliographic references. A wide range of values was mined for most of the attributes. Permeation data for 11 gases were collected and five major types of membranes are present: polymer, zeolite, MMM, CMS, MOF, and ceramic. Most of the attributes had an insignificant linear correlation with gas permeability (including film thickness, pore size, temperature, and pressure), indicating a complex and contextually specific relationship. Total Pore Volume, Micropore Volume, and BET Area attributes were the morphological attributes that are most linearly correlated with gas permeability and can be good performance indicators for membranes, regardless of the material type. It is expected that the results presented will be useful to guide decision-making in the steps of designing new membranes for gas separation in a big picture context.

“…Method 1 usually utilizes nitrogen-containing ligands to coordinate divalent metals, and polydentate N -heterocycles, such as imidazole, tetrazole, triazole, and pyrazole, are often used as nitrogen donors. Imidazole-based ligands are amphoteric, highly polar, and can easily accept or donate protons, providing sites for noncovalent interactions or additional coordination. − In addition, imidazole-based MOFs show excellent structural diversity and high hydrothermal and chemical stability. Furthermore, the tunability of the pore structure and the variability of the functional groups offer possibilities for monitoring and sensing. , …”

An imidazole-functionalized metal−organic framework (MOF), {[Ba 2 L (H 3 CCOO) (DMF) 2 ] (DMF)} n , denoted as HBU-168, has been synthesized and characterized by single-crystal X-ray diffractometry. The synthesized MOF exhibits ligand-based luminescence, which can be attributed to coordination effects. Due to its excellent fluorescence performance, HBU-168 can be used to detect nitroaromatic compounds (NACs) and metal ions selectively and sensitively. The most striking properties of HBU-168 are the distinct red shift (∼34.8 nm) observed in the presence of picric acid (PA) with a Stern−Volmer constant (K SV ) of 4.17 × 10 4 . The mechanism of the change in luminescence in the presence of PA is determined by experiments and density functional theory calculations. The results indicate that the electron transfer between PA and the MOF has a reduction in the frontier orbital energy gap. Subsequently, HBU-168 is used to prepare a light-emitting-diode-based sensor (denoted HBU-168-LED), which can detect PA rapidly and visually. In addition, we find that HBU-168 can be used to detect metal ions, particularly magnesium ions. The metal detection mechanism is based on the turn-on fluorescence of HBU-168 caused by weak interactions between the MOF and metal ions. Finally, HBU-168 is found to be a good adsorbent for Congo red, achieving a removal efficiency of 98.89%. Therefore, the multifunctional HBU-168 MOF is a promising luminescent sensor and adsorbent.

Metal‐organic frameworks (MOFs) are promising porous materials that have huge potential for gas separation when put in the membrane configuration. MOFs have huge potential of the MOFs such as excellent pore size, ease of tuning the pore chemistry, higher surface area, and chemical and thermal stabilities, MOFs have been explored for various gas separation and storage applications. This review discusses various approaches for fabricating MOFs‐based membranes for the separation of H2 gas from a variety of feeds having various gases CO2, CO, N2, and CH4 as impurities. The emphasis has been put on three types of membranes for H2 separation which include MOFs‐based hollow fibrous/tubular/disk membranes, MOFs‐based mixed matrix membranes (MMMs), and MOFs‐based stand‐alone membranes. In addition, various challenges such as reducing inhomogeneity between MOFs and polymeric matrices have also been discussed. Similarly, the approaches to successfully decorating MOFs on different supports in different configurations have been explained. The possible ways of improving the MOFs‐based membranes for H2 have also been discussed.
