Consequently, unequivocal identification as the crystalline MOF-74 phase was deduced by combining other characterization techniques rather than powder X-ray diffraction. These small crystals are unstable as isolated ones, so they form steady and robust aggregates, whose mechanical properties strongly depend on the crystal size.
6 (b)). The powder X-ray diffraction patterns of MM-MOF-74 were identical with those of single-metal MOF-74, and no amorphous phases were found by scanning electron microscopy. The successful preparation of guest-free MM-MOF-74 samples was confirmed by N2adsorption measurements.

Electronic Supplementary Material (ESI) for Energy & Environmental Science The evolution of the Mg-MOF-74 membrane formation is also characterized by XRD, as shown in Fig. 6, compared with the XRD patterns of Mg-MOF-74 powder (Fig. 6 (a)). After an elapse of 16 h, the first peaks of the Mg-MOF-74 crystals have been detected on the support surface (Fig. 6 (b)). The powder X-ray diffraction patterns of MM-MOF-74 were identical with those of single-metal MOF-74, and no amorphous phases were found by scanning electron microscopy.
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). However, mesopores were formed, probably due to the competitive binding of TEA to Mg 2+ ions, and the average particle size of the former (ca. 0.6 μm) was significantly smaller than that of

The pattern. of 1 is well-matched to that for Postsynthetic functionalization of magnesium 2,5-dihydroxyterephthalate (Mg-MOF-74) with tetraethylenepentamine (TEPA) resulted in improved CO2 adsorption performance under dry and humid conditions. XPS, elemental analysis, and neutron powder diffraction studies indicated that TEPA was incorporated throughout the MOF particle, although it coordinated preferentially with the unsaturated … MOF-74 and TEPA-modi fi ed Mg-MOF-74.

Metal–organic frameworks (MOFs) are one of the most intensely studied material types in recent times. Their networks, resulting from the formation of strong bonds between inorganic and organic building units, offer unparalled chemical diversity and pore environments of growing complexity.
