than that of Mg-MOF-74 (2.39 mmol/g) under the same condition. XRD patterns and SEM images of the composites demonstrate that the hydrothermal stability and CO 2 adsorption performance of the composites were improved compared with those of pristine Mg-MOF-74 after hydrothermal treatment. 1. INTRODUCTION Metal−organic frameworks (MOFs) are one The transformation was monitored in detail by a combination of XRD, in situ XAFS, and XPS measurements. Ni NPs prepared from Ni‐MOF‐74 were easily reduced by the generation of reducing gases accompanied by the decomposition of Ni‐MOF‐74 structures during heat treatment at over 300 °C under N 2 flow.

The formation of Mg-MOF-74 was confirmed by the presence of the characteristic peaks at 6.7°, 11.7° and 18° of MOF-74 in each XRD pattern,. In addition, the broad peaks observed in XRD pattern for the synthesis with DMF only (F1) suggests that nano-crystals are produced. High-quality Co-MOF-74 crystals were successfully synthesized in 1 h by microwave heating (Co-MOF-74 (M)). The XRD pattern and textural properties of Co-MOF-74 (M) including the BET surface area (1314 m 2 g −1) were virtually identical to those of a sample synthesized in 24 h by the solvothermal method (Co-MOF-74 (S), 1327 m 2 g −1). The crystallinity of the MM-MOF-74 series was confirmed by PXRDanalysis(Figure1).AllPXRDpatternsoftheMM-MOF-74 series coincide with the calculated PXRD pattern of the parent MOF-74 structure, indicating that the topology is retained and thus all members are isostructural. To exclude the possibility of Despite the fact that, in the case of Zn-MOF-74, XRD analyses revealed a characteristic pattern for MOF-74 crystals at the metallic support, deep analysis of the SEM pictures for individual depositions shows that the well-defined crystals are formed after triple deposition (Fig.

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 … Of the current MOF materials, MOF-74 presents the unique advantage of coordinatively unsaturated (open) metal sites that can be varied without affecting the underlying framework struc-ture (Scheme 1). Thus, it is possible to test the effect of the metal center on the gas separation properties of MOF-74.
