These small crystals are unstable as isolated ones, so they form steady and robust aggregates, whose mechanical properties strongly depend on the crystal size. Feb 24, 2014 · area values for MM-MOF-74 are slightly lower than those for Mg-MOF-74 [1490 (1350) m2/g] because it is 20−30% lighter than MM-MOF-74. Nevertheless, the porosity measurement data clearly supports the fact that the MOF pores were successfully activated and guest molecules, including free metal ions, were removed. 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 N 2 adsorption measurements. May 15, 2014 · Metal organic frameworks (MOFs) are emerging potential materials for catalytic applications.

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. Caskey et al.
