  溶剂诱导的柔性金属有机框架中呼吸行为的控制，以实现天然气的输送

  摘要：

  寻找合适的刺激物来控制金属-有机金属框架（MOF）的呼吸行为非常具有挑战性。在此，我们报告了溶剂诱导的MIL-53系列（一组灵活的MOF）在不同呼吸阶段的粒径和稳定性的变化。调节水/二甲基甲酰胺（DMF）的比例以合成具有不同行为的MIL-53系列成员。通过高压甲烷吸附测试来探索呼吸。DMF浓度的增加会降低MOF的粒径，并增加多孔相的稳定性，从而增加天然气输送所需的5.8–65 bar的甲烷吸附差。

  a building block is shown to undergo chemical modification with a set of cyclic anhydrides. The modification of the aluminum-based MOF known as MIL-53(Al)-NH2 (MIL = Matérial Institut Lavoisier) by these reagents is demonstrated by using a variety of methods, including NMR and electrospray ionization mass spectrometry (ESI-MS), and the structural integrity of the modified MOFs has been confirmed by

  MIL-53 represents one of the most notable metal–organic frameworks given its unique structural flexibility and remarkable thermal stability. In this study, a shaker-type ball milling method has been developed into a facile and generalizable synthetic strategy to access a family of MIL-53 type materials under ambient conditions. During the explorations of [M(OH)(fumarate)] (M = Al, Ga, and In), we report

  This paper reports for the first time iodobenzene methoxycarbonylation over Pd-containing catalysts based on MOF materials differed in topology, texture properties and organic and inorganic building blocks: MIL-53(Al) (AlOHbdc, bdc = benzene-1,4-dicarboxylate), NH2-MIL-53(Al) (AlOHabdc, abdc=2-aminobenzene-1,4-dicarboxylate), NH2-MIL-101(Al) (Al(3)Oabdc)(3), and ZIF-8 (Zn(Melm)(2). Melm = 2-methylimidazolate). Low-loaded nanocatalysts (0.1-0.5 wt.% Pd) based on MIL-53(Al) and ZIF-8 demonstrated a superior activity as compared to those on conventional supports such as silica and alumina. The catalytic performance of the synthesized nanocatalysts is affected both by the MOF support nature and Pd loading. Another important factor governing the performance of the Pd/MOF catalysts is the preparation procedure of the metal-organic matrices which affects their crystal size and morphology. This effect was studied for ZIF-8 materials. (C) 2018 Published by Elsevier Ltd.

  We present a combined in situ small-and wide-angle scattering (SAXS/WAXS) study on the crystallization of two topical metal-organic frameworks synthesized from similar metal and organic precursors: NH2-MIL-53(Al) and NH2-MIL-101(Al). A thorough analysis of SAXS data reveals the most important phenomena occurring during crystallization and unravels the effect of the solvent. NH2-MIL-53(Al) growth follows two routes: (i) through direct hydrolysis of AlCl3 center dot 6H(2)O in water, and (ii) via the intermediate NH2-MOF-235(Al), which forms in pure DMF or DMF/H2O mixtures. In the case of pure H2O as solvent, formation of NH2-MIL-53(Al) crystals proceeds through steady growth in all three dimensions. The addition of DMF to the synthesis mixture results in amorphous scattering entities forming very rapidly and subsequently arranging into the intermediate phase, NH2-MOF-235(Al). In DMF/H2O mixtures, amorphous precursors develop in rapid fashion with fractal character dominating, followed by densification, crystallization of NH2-MOF-235(Al) and slow transformation into NH2-MIL-53(Al). Formation of NH2-MIL-101(Al) only occurs when pure DMF is used as solvent, and it always proceeds through the formation of the intermediate NH2-MOF-235(Al). In this case a smooth scatterer surface is observed, with morphology and size constant in time. (C) 2012 Elsevier B.V. All rights reserved.
