Our ab initio calculations are at the density functional theory level using the van der Waals including density functional vdW-DF. @article{osti_1492034, title = {Ab Initio Derived Force Fields for Predicting CO2 Adsorption and Accessibility of Metal Sites in the Metal–Organic Frameworks M-MOF-74 (M = Mn, Co, Ni, Cu)}, author = {Haldoupis, Emmanuel and Borycz, Joshua and Shi, Huiliang and Vogiatzis, Konstantinos D. and Bai, Peng and Queen, Wendy L. and Gagliardi, Laura and Siepmann, J. Ilja}, abstractNote = {Metal Metal–organic frameworks (MOFs) containing more than two kinds of metal ions mixed in one secondary building unit are rare because the synthesis often yields mixed MOF phases rather than a pure phase of a mixed-metal MOF (MM-MOF). In this study, we use a one-pot reaction to make microcrystalline MOF-74 [M2(DOT); DOT = dioxidoterephthalate] with 2 (Mg and Co), 4 (Mg, Co, Ni, and Zn), 6 (Mg A Fe-containing metal-organic framework, Fe-MOF-74, was solvothermally synthesized using FeCl2.4H2O and 2,5-di-hydroxy-1,4-benzenedicarboxylic acid. Characterization was conducted by XRD, BET surface area measurement, FT-IR spectroscopy, TGA, and elemental analysis, which confirmed successful prepar … A greener synthesis of Cu-MOF-74 was obtained, for the first time, in methanol as the unique solvent and at room temperature. 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 The values of MOF-74-2 and MOF-74-3 at 273 K and 1 bar decrease to 93 and 143, respectively.

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 , .

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.
