Abstract
In this work, we report the fabrication of MgAl- layered double hydroxide (LDH) supported copper based metal organic framework (MOF) nanocomposite via a facile solvothermal method. Reaction of pre-synthesized benzene-1,4-dicarboxylate ions (BDC) intercalated MgAl-LDH with Cu(II) ions produce paddle-wheel like Cu-(BDC) MOF nanocrystals on the surface of MgAl-LDHs. The structures and morphology of the synthesized new materials have been investigated by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), UV–visible and photo luminescent spectroscopy, Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA). The adsorption characteristics of the synthesized material showed the dye removal efficiency over 99% after 20 min with an adsorption capacity of 600 mg/g.
