Bottom Adsorption-desorption cycling of C02 for 1-en showing reversible uptake from (a) simulated air (0.39 mbar C02 and 21% 02 balanced with N2) and from (b) simulated flue gas (0.15 bar C02 balanced with N2). (c) time-dependent C02 adsorption for porous materials (A = 1-en, B = mmen-Mg2(dobpdc), C = 1, D = Mg-MOF-74, E = Zeolite 13X, F = MOF-5). (d) C02 adsorption ratio of 1-en in flue gas (after 6 min exposure to 100% RH at 21 °C) to 1-en in flue gas (Adapted from [192]).

Several MOFs as UIO-66, UIO-ee-NH, Mg-MOF-74, MIL-101, CuBTC, ZIF-8, IRMOF-3, and MOF-5 with different acid-base properties were tested as catalysts for the synthesis of styrene carbonate (SC) from styrene oxide (SO) with CO using a high-pressure batch reactor [116].

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)). ... 

DFT studies have been carried out to demonstrate the bonding of CO2 to Metal Organic Frameworks (MOF). A bridged coordination has been proposed by Hou et al. [22] in the interaction of CO2 with M-MOF-74 (M = Mg and Zn), which shows a high CO2 adsorption capacity. Metal ions are supposed to interact with the O atoms of CO2, whereas the carbon atom of CO2 gives strong interactions with the O atoms of the organic linkers of the MOF.

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...
