Synthesis and gas sorption properties of a metal-azolium framework (MAF) material.

چکیده
A new strut containing an imidazolium tetracarboxylic acid core has been successfully incorporated into a microporous material using paddlewheel-coordinated copper(II) ions as nodes. Sorption studies conducted on this permanently microporous material imply that it can separate carbon dioxide from methane with high selectivity.

Synthesis of Nanoporous Metal Organic Framework MIL-53-Cu and Its Application for Gas Separation
MIL-53-Cu has been synthesized hydrothermally and has been used for the first time for gas separation. MIL-53-Cu shows adsorption capacities of 8.1, 0.7 and 0.5 m.mol/g, respectively, for CH4, CO2 and H2 at 30 bar and 298 K. The high CH4 adsorption capacity of MIL-53-Cu maybe attributed to the high pore volume and large number of open metal sites....
متن کاملDioxole functionalized metal-organic frameworks.
The synthesis and physical properties of dioxole functionalized metal-organic frameworks (MOFs) are reported. Combination of benzo[d][1,3]dioxole-4,7-dicarboxylic acid (dioxole-BDC) and Zn(II) under solvothermal conditions yields either an isoreticular metal-organic framework analog (IRMOF-1-dioxole) or a new MOF material (MOF-1-dioxole). With the addition of a co-ligand, namely 4,4'-bipyridine...
متن کاملEnhanced gas sorption properties and unique behavior toward liquid water in a pillared-paddlewheel metal-organic framework transmetalated with Ni(II).
The synthesis of a permanently porous pillared-paddlewheel metal-organic framework (MOF) was achieved through transmetalation of Zn(II) with Ni(II). The MOF can be treated with liquid water, leading to the reversible displacement of 50% of its pillars by water molecules and resulting in a most unusual crystalline and permanently porous structure.

A highly stable porous lanthanide metal-organic framework, Y(BTC)(H2O).4.3H2O (BTC = 1,3,5-benzenetricarboxylate), with pore size of 5.8 A has been constructed and investigated for hydrogen storage. Gas sorption measurements show that this porous MOF exhibits highly selective sorption behaviors of hydrogen over nitrogen gas molecules and can take up hydrogen of about 2.1 wt % at 77 K and 10 bar...

Objective(s): According to the unique properties of magnetic nanoparticles, Nickel Metal-Organic Frameworks (MOF) was synthesized successfully by ultrasound irradiation. Metal-organic frameworks (MOFs) are organic–inorganic hybrid extended networks that are constructed via covalent linkages between metal ions/metal clusters and organic ligands called a linker. Materials and Methods: The nanopar...
