Metal–organic frameworks (MOFs) can play a decisive role owing to their outstanding performances regarding gas selectivity and sensitivity. The tetrathiafulvalene (TTF)-infiltrated MOF, Co-MOF-74, has been prepared following the host–guest concept and evaluated Cu-MOF-74 is an active catalyst in the Friedel–Craft acylation of anisole. • Polar solvents diminish the activity of the open metal sites in Cu-MOF-74. • Cu-MOF-74 phase is stable using low concentration of acylating agent. • Cu-MOF-74 shows a better catalytic performance than ZSM-5 and Al-MCM-41 materials. Jan 15, 2011 · The Mg-MOF-74 material loads 1.6 times the capacity of 13X zeolite and the Ni-MOF-74 loads at 48% of the capacity of 13X zeolite, when the zeolite is regenerated under these conditions. The 13X gains performance under these regeneration conditions, but significantly more energy is required relative to the MOF samples.

Nanocrystals of Mg-MOF-74 have been immobilized into the mesopores of SBA-15 rods to fabricate [email protected] hybrid materials. To furnish such composites, a relatively simple synthetic strategy has been adopted by direct dispersion of the metal-organic framework (MOF) precursors in SBA-15 matrix to prepare the hybrid materials in situ. @article{osti_1378737, title = {In silico design and screening of hypothetical MOF-74 analogs and their experimental synthesis}, author = {Witman, Matthew and Ling, Sanliang and Anderson, Samantha and Tong, Lianheng and Stylianou, Kyriakos C. and Slater, Ben and Smit, Berend and Haranczyk, Maciej}, abstractNote = {Here, we present the in silico design of metal-organic frameworks (MOFs MOF-74. Gas sorption studies indicate that UTSA-74 takes up a large amount of acetylene of 152 cm 3/cm under ambient conditions, which is comparable to that of Zn-MOF-74; however, to our great surprise, UTSA-74 adsorbs a much smaller amount of carbon dioxide (90 cm 3/cm ) than Zn-MOF-74 (146 cm 3/cm ).

Full characterisation of the MOF material showed its purity and also its nanocrystalline nature. Complete activation (150 °C for 1 h and 10−3 bar) of Cu-MOF-74 afforded unsaturated Cu Jul 15, 2018 · The values of MOF-74-2 and MOF-74-3 at 273 K and 1 bar decrease to 93 and 143, respectively. However, the selectivity of MOF-74-1 for CO 2 /N 2 becomes better as the pressure increasing, and the value is up to 223 at 1 bar, which may be attributed to the presence of mesopores from the interstitial voids among the large particles , . In this paper, a core–shell ZIF-67@Co-MOF-74 catalyst was synthesized by coating 2,5-dihydroxyterephthalic acid (DHTP) molecules on the surface of ZIF-67 crystals via the ligand exchange method. Notably, the ZIF-67@Co-MOF-74 catalyst with shell thicknesses of 10 nm, 25 nm and 50 nm can be further obtained by In this work, Mn-MOF-74 with hollow spherical structure and Co-MOF-74 with petal-like shape have been prepared successfully via the hydrothermal method.
