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.

The fine-tuning of metal-based molecular building blocks in Zn-MOF-74 through post-synthetic cation exchange with Ca2+ significantly enhances its basicity and corresponding catalytic performance. The resulting material, exemplified by Ca/Zn-MOF-74, is shown through Knoevenagel condensation to give an improve Zn‐MOF‐74: The MOF was prepared by following the procedure reported recently. 59 0.950 g (3.19 mmol) of zinc nitrate hexahydrate and 0.405 g (2.04 mmol) of 2,5‐dihydroxybenzene‐1,4‐dicarboxylic acid were mixed in a mixture of 25 mL of dimethylformamide (DMF), 3 mL of ethanol and 3 mL of water. The solution was stirred for 30 minutes Isostructural MOF-74 (M = Ni, Mg) were successfully synthesized with both hydrothermal method (1 and 3) and microwave-assisted method (2 and 4). These MOF-74 samples were characterized with scanning electron microscopy for crystal structure, powder X-ray diffraction for phase structure, and nitrogen adsorption for pore textural properties. Nanocrystals of Mg-MOF-74 have been immobilized into the mesopores of SBA-15 rods to fabricate [email protected] hybrid materials.

Sep 01, 2008 · Here we report rapid, simple, and high yielding room temperature syntheses for some important MOFs: MOF-5, MOF-74, MOF-177, and MOF-199 (HKUST-1) ().These MOFs were chosen because they represent a cross-section of desirable properties such as ultrahigh porosity (MOF-5 and MOF-177), one dimensional pores (MOF-74), and open metal sites (MOF-74 and MOF-199); attributes that have implications in Mg-MOF-74 crystals were successfully prepared in 1 h by a sonochemical method (Mg-MOF-74(S)) after triethylamine (TEA) was added as a deprotonating agent.Mg-MOF-74(S) (1640 m 2 g −1 BET surface area) displayed similar textural properties to those of a high-quality MOF sample synthesized in 24 h by the solvothermal method (Mg-MOF-74(C), 1525 m 2 g −1). obtain the Zn-MOF-74 material containing open metal sites. Considering that the molecular size of d,l-Pro enables its diffu-sion within the pores of Zn-MOF-74, we anticipated that the chiral amino acid might coordinate to the Zn2+ ions in amon-odentate manner via its carboxylate group or bidentate, bridg- Nanocrystals of Mg-MOF-74 have been immobilized into the mesopores of SBA-15 rods to fabricate Mg-MOF-74@SBA-15 hybrid materials.

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
