  • Hydrogen Isotope Separation in Metal-Organic Frameworks

    M-MOF-74 represents a family of isostructural MOFs, where M is a placeholder for one of six metals including manganese, iron, cobalt (Co), nickel, copper, and zinc. In this project, we focus our investigation on Co-MOF-74 and speci cally the (dobdc) allotrope, where (dobdc) denotes the organic ligand 2,5-dioxido-1,4-benzenedicarboxylate.

    Abstract Room temperature synthesis of metal-organic frameworks (MOFs) has been developed for four well-known MOFs: MOF-5, MOF-74, MOF-177, and MOF-199. A new isoreticular metal framework (IRMOF), IRMOF-0, having the same cubic topology as MOF-5, has been synthesized from acetylenedicarboxylic acid using this method to accommodate the thermal sensitivity of the linker.
