Ni-MOF-74

Figure 7 The functionalization of MOFs and their interactions with COj. (a) The crystallographic structure of Ni-MOF-74 in the presence of COj, where the CO2 coordinates to unsaturated nickel centers in an end-on manner. (b) The introduction of Lewis base (mmen) into an analogous Mg-MOF with larger cavities, where the mmen coordinates to the unsaturated magnesium centers.

The dobdc ligand (Figure 9.36d) shows remarkable versatility for metal-organic frameworks. MOFs of the general formula M2(dobdc) (M = Mg, Mn, Fe, Co, Ni, Zn) have been prepared. The chemical and physical properties of M2(dobdc) MOFs are heavily influenced by the specific metal ion incorporated. Figure 9.40 shows a two- and three-dimensional perspective of the pores formed by Zn-MOF-74 (Zn2(dobdc)). ...

Bae et al. [114] performed a study to modify Ni-DOBDC with pyridine molecules. The study showed that pyridine molecule made the normally hydrophilic internal surface more hydro-phobic as a result, water absorption was reduced, while substantial C02 capture capacity was retained to a certain level. Fracaroli et al. [132] improved the interior of IRMOF-74TII by covalently functionalizing it with a primary amine, and used a MOF, IRMOF-74-IIICH2NFI2, for the selective capture of C02 in 65% relative humidity. 

To investigate the role of OMSs in methane adsorption and the influence of the speciflc metal on the properties of the materials, in 2009, Zhou and coworkers studied methane adsorption in a series of MMOF-74 materials (M = Mg, Mn, Co, Ni, Zn), one of the most well-studied families of MOFs bearing the highest concentration of OMSs reported so far. ZnMOF-74 was...
