Organic Framework

In this paper, we report the synthesis of metal organic framework of uranium 1,2,4,5-benzene tetracarboxylic acid (U-H4btec MOF) by solvothermal method. The obtained MOF was characterized by Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), X-ray diffraction spectroscopy (XRD), Energy dispersive spectroscopy (EDS), thermogravimetric and differential thermogravimetric analysis (TGA/DTA). The morphology of the uranium 1,2,4,5-benzene tetracarboxylic acid MOF observed by SEM, revealed the presence of flaky porous structure. Adsorption of Cr3+ from aqueous solution onto the uranium 1,2,4,5-benzene tetracarboxylic acid MOF was systematically studied. Langmuir and Freundlich adsorption isotherms were applied to determine the adsorption capacity of the MOF to form a monolayer. Kinetic determination of the adsorption of Cr3+ suggested both chemisorption and physisorption probably due to the presence of carbonyl groups within the MOF and its porous structure.

Organic Framework

A porous crytalline metal-organic framework Fe3O(BPDC)3 was synthesized, and its properties were characterized by various techniques, including X-ray powder diffraction (PXRD), Fourier transform infrared (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and nitrogen physisorption measurements. The Fe3O(BPDC)3 was used as an efficient catalyst for the oxidative coupling reaction of benzaldehyde and (E)-1-phenylethan-1-one O-acetyl oxime to form 2,4,6-triphenylpyridine as desired product. The reaction could proceed readily, with more than 83 % reaction yield being achieved after 360 min at 140 oC in the presence of 10 mol% Fe3O(BPDC)3) catalyst and Di-tert-butyl peroxide as an oxidant. This Fe-MOF exhibited higher activity than other MOFs and traditional homogeneous catalysts in the oxidative coupling reaction. The transformation could only proceed to obtain main product in the presence of Fe3O(BPDC)3.
