Mixed ligand based metal organic frameworks synthesis characterization and applications

Abstract

The present thesis incorporates the synthesis of mixed-ligand based metal-organic frameworks using various O and N donor ligands with transition metal ions. The MOFs were synthesized using solvothermal method. The synthesized ligands and MOFs were characterized using various techniques such as FTIR, 1H NMR, TGA, DSC, SCXRD, PXRD, elemental analysis etc. The MOFs have been proved to be interesting compounds with intriguing structures, tunable properties and expedient applications. So, the synthesized MOFs were explored for their potential applications in adsorption of gases such as CO2, N2; adsorption of dyes like Reactive black 5 (RB5), Methyl Orange (MO) and Orange G (OG) in aqueous system; sensing of heavy metal ions such as Zr(IV) and Hg(II) in water using MOFs fluorescence and nanozyme based sensors. The results obtained were quite promising and supported by techniques like UV-Vis, Fluorescence, EDS, SEM, TEM, XPS etc. Thus, new materials for removing various contaminants from the environment were obtained, which is extremely important for the preservation of life on earth. newline
