A nanoscale Cu-metal organic framework with Schiff base ligand: Synthesis, characterization and investigation catalytic activity in the oxidation of alcohols

Abstract

Nanostructures of a new copper-based metal-organic framework with a Schiff base ligand as an organic linker, Cu2 (bdda) (OAc)2·1H2O (H2bdda=4,4′-[benzene-1,4-diylbis (methylylidenenitrilo)] dibenzoic acid), was prepared via Ultrasound assisted synthesis and characterized by X-ray powder diffraction (XRD), thermogravimetric analysis (TGA), Brunauer–Emmett–Teller (BET), inductively coupled plasma atomic emission spectroscopy (ICP-AES), transmission electron microscope (TEM), elemental analysis (CHN) and FT-IR spectroscopy. Catalytic proficiency of this MOF in the oxidation of alcohols was investigated that exhibited efficient and selective activity for the transformation of alcohols to the corresponding carbonyl compounds under the absence of organic solvents. The reusability of the catalyst also was examined, in which the catalyst was reused six times without significant loss of its catalytic efficiency.
