Synthesis and Characterization of 2D Metal-Organic Frameworks for Adsorption of Carbon Dioxide and Hydrogen

The reaction of Cd(NO(3))(2)·4H(2)O and Zn(NO(3))(2)·6H(2)O with the bipyridyl dicarboxylate ligand H(2)bpydc (2,2′-bipyridine-4,4′-dicarboxylic acid) afforded two porous metal organic frameworks [Cd(bpydc)(2)(DMF)(2)·2DMF](n) (JMS-3) and [Zn(bpydc)(DMF)·DMF](n) (JMS-4). X-ray diffraction studies re...

description The reaction of Cd(NO(3))(2)·4H(2)O and Zn(NO(3))(2)·6H(2)O with the bipyridyl dicarboxylate ligand H(2)bpydc (2,2′-bipyridine-4,4′-dicarboxylic acid) afforded two porous metal organic frameworks [Cd(bpydc)(2)(DMF)(2)·2DMF](n) (JMS-3) and [Zn(bpydc)(DMF)·DMF](n) (JMS-4). X-ray diffraction studies revealed that both JMS-3 and JMS-4 crystallize in the monoclinic crystal. The MOFs possess 2D interdigited networks with (sql) topology. Sorption studies showed that the activated phase of JMS-3 had CO(2) volumetric uptakes of 26.50 and 30.89 cm(3) (STP) g(−1) (1.18 and 1.39 mmol g(−1)) whist JMS-4 gave 10.96 and 16.08 cm(3) (STP) g(−1) (0.49 and 0.71 mmol g(−1)) at 298 and 273 K respectively.
