Acetylene Adsorption on CPO‐27‐M Metal–Organic Frameworks (M=Fe, Co and Ni)

Microporous metal–organic frameworks for storage and separation of small hydrocarbons

“…5c), which was further confirmed by the first-principle calculations. It 15 should be mentioned that NiMOF-74 exhibits significantly decayed adsorption of acetylene, which was further investigated in detail by Chaven et al 74 The strongest binding of acetylene within NiMOF-74-Ni can be associated to the strong polarizing centers provided by NiMOF-74 due to the small ionic radius of 20 Ni 2+ (83 pm) and but does not lead to C 2 H 2 polymerization under low-pressure conditions.…”

Microporous metal-organic frameworks with suitable pore spaces for acetylene storage and purification

“…As a relatively new family of porous materials, metal-organic frameworks (MOFs), which can be readily self-assembled from their corresponding metal ions or metal-containing clusters with suitable organic linkers, have been widely explored for acetylene storage [8][9][10][11][12][13] and separation [14][15][16][17][18][19][20][21][22]. By immobilizing specific sites, such as open metal sites [23,24] and Lewis acidic and basic sites [25,26] into the frameworks, either high acetylene storage capacity or separation capacity has been reached in dozens of MOFs, but there are a few MOFs which exhibit both high acetylene storage capacity and separation capacity at the same time [27,28].…”

Metal-dioxidoterephthalate MOFs of the MOF-74 type: Microporous basic catalysts with well-defined active sites

“…[22] The high density of exposed metal ions in these materials has sparked much interest in the field of adsorption and the adsorptive separation of compounds such as CO, CO 2 , CH 4 , ethane, acetylene, propane, propylene or H 2 S. [20,[23][24][25][26][27][28][29][30][31] The existence of a family of isostructural materials has also allowed to study the specific role of the metal ion in these adsorption processes. [20,24,29,32] Reports of catalysis using M 2 dobdc are very limited hitherto; they focus on the role of the metal ion as a Lewis acid center, or in accelerating autoxidation reactions. [22,33,34] …”
