The effect of pore structure in ethane-selective metal-organic frameworks for ethylene purification

A novel hydrophobic carborane-hybrid microporous material for reversed C2H6 adsorption and efficient C2H4/C2H6 separation under humid conditions

“…5A shows that high-purity C 2 H 4 (>99.9%) was obtained between 44 and 58 min. The polymer grade C 2 H 4 (>99.9%) productivity is estimated to be as high as 14.5 L kg −1 (647 mmol kg −1 ), superior to those of NKU-301 (9.5 L kg −1 ), 14 Zr-TCA (6.51 L kg −1 ), 25 MOF-801 (5.73 L kg −1 ), 26 UiO-66 (0.46 L kg −1 ) 25 and many other popular materials under the same conditions. 11 Besides, ZNU-10 displays high recyclability and resistance to humidity.…”

Friends or Foes: Fundamental Principles of Th-Organic Scaffold Chemistry Using Zr-Analogs as a Guide

“…Broad chemical and thermal stability is one of the highly sought-after traits in the field of metal–organic frameworks (MOFs − ), which shapes the landscape of possible applications with a main focus on specific MOF classes, including those based on zirconium. − Indeed, Zr-MOFs (e.g., possessing fcu- , and ftw-type , topologies) exhibit excellent thermostability up to 500 °C, possess chemical stability across a wide pH range from 2 to 12, and demonstrate exceptional resilience even under 423 Gy/min γ radiation . At the same time, the recent and rapidly growing interest in the development of fuel cycle reactors, radiological daughters for nuclear medicine, and efficient nuclear stockpile recycling serves as the driving force for translating the wealth of fundamental knowledge acquired for Zr-MOFs to thorium-based analogs. − Since the onset of research focusing on Th-based materials, Zr-frameworks have been considered to be the closest analogs due to the shared metal oxidation state (+4), high Lewis acidity, formation of strong coordination bonds to carboxylate-based organic linkers, and oxophilicity comparable to thorium. − However, in contrast to a plethora of publications (>3600) focusing on Zr-MOFs, only around 100 exist for their Th-based counterparts (Figure ).…”

Toward Scalable and Sustainable Synthesis of Metal–Organic Frameworks

“…Conventionally, MOF-801 is synthesized overnight under solvothermal conditions, using DMF as a solvent. In a recent development, Li et al introduced a simple and rapid synthesis method, successfully scaling up the production of MOF-801 to 10 g through facile, one-pot reactions at 130 °C (Figure e) . High-quality and reproducible samples of MOF-801 were prepared within just 20 min.…”

“…In a recent development, Li et al introduced a simple and rapid synthesis method, successfully scaling up the production of MOF-801 to 10 g through facile, one-pot reactions at 130 °C (Figure 2e). 24 High-quality and reproducible samples of MOF-801 were prepared within just 20 min. However, the interest in lower energy cost and safer conditions has stimulated exploration into the green synthesis of MOFs at or near room temperature.…”

“…Noteworthy success includes the commercialized production of several prototype MOFs such as ZIF-8 (zinc 2-methlimidazolate, Zn­(MeIm)), HKUST-1 (copper benzene-1,3,5- tricarboxylate, Cu-BTC), and MIL-53 (aluminum benzene-1,4-dicarboxylate, Al-BDC) by BASF. In the pursuit of scale-up synthesis in research laboratories, MOF-801, MOF-5, NU-1000, UiO-66­(NH 2 ), , ZU-901, MIL-53, ZIF-8, and CALF-20 have been obtained in multigrams to kilograms. MOF-303, a sorbent with significant technological potential for water harvesting, has emerged as a promising candidate due to its ability to absorb water vapor at low relative humidity (RH) and to release it with mild heating .…”
