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

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. 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 work, Mn-MOF-74 with hollow spherical structure and Co-MOF-74 with petal-like shape have been prepared successfully via the hydrothermal method. The catalysts were characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), thermogravimetry–mass spectrum analysis (TG-MS), N2 adsorption/desorption, scanning electron microscopy (SEM), and X-ray 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 A new metal–organic framework Zn2(H2O)(dobdc)·0.5(H2O) (UTSA-74, H4dobdc = 2,5-dioxido-1,4-benzenedicarboxylic acid), Zn-MOF-74/CPO-27-Zn isomer, has been synthesized and structurally characterized. It has a novel four coordinated fgl topology with one-dimensional channels of about 8.0 Å. Unlike metal sites in the well-established MOF-74 with a rod-packing structure in which each of them Mg-MOF-74 is a metal organic framework with the highest CO 2 adsorption capacity of any porous material.

The quality of the produced sample was evaluated by gas adsorption performance using CO2 at 1 bar and 25 °C Two MOF-74 analogs with OH groups on 1D channel surfaces have been synthesized through multi-component self-assembly at room temperature. Their guest-free forms demonstrate a potential luminescent In contrast with MOF‐74 with fully deprotonated and symmetrically bonded 2,5‐dihydroxyterephthalic acid (H 4 DOBDC), H 4 DOBDC adopts an unusual nonsymmetric bonding mode in CPM‐72 (carboxylate only at one end and carboxylate/phenolate at the other), resulting in a highly porous and intrinsically chiral 3D framework.

Unlike metal sites in the well-established MOF-74 with a rod-packing structure in which each of them Mg-MOF-74 is a metal organic framework with the highest CO 2 adsorption capacity of any porous material. Therefore, it has been suggested for CO 2 separations as both an adsorbent and incorporated into membranes. Design of the Mg-MOF-74 crystal morphology is important to expand the applicability of the material. 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 synthesis of Mn79.88Fe20.12-MOF-74 is similar to that of Mn-MOF-74 but using MnCl2 (120 mg, 0.954 mmol) and FeCl2 (10 mg, 0.079 mmol). The product was almost 50.4 mg. Synthesis of Mn63.20Fe36.80-MOF-74 The synthesis of Mn63.20Fe36.80-MOF-74 is similar to that of Mn-MOF-74 but using MnCl2 (110 mg, 0.874 mmol) and FeCl2 (20 mg, 0.158 mmol Lastly, we conclude that the increased stability of Mg–Ni-MOF-74 is a result of a M–O bond length distortion in mixed-metal MOF-74, consistent with recent work on the stability of MOF-74 under water exposure.}, doi = {10.1021/acs.jpcc.6b11719}, journal = {Journal of Physical Chemistry.
