Facile Synthesis of MgAl-Layered Double Hydroxide Supported Metal Organic Framework Nanocomposite for Adsorptive Removal of Methyl Orange Dye

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 thermo-gravimetric 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.
