In-Situ synthesis of Metal-Organic Framework (MOF) on Layered Double Hydroxide (LDH) for Adsorptive Removal of Evans Blue Dye
Synopsis
In this work, we report the synthesis of a new hybrid material based on MOF-ZnPA (MOF: Metal Organic Framework, Zn: Zinc, PA: Pyromellitic Acid) and Co-Zn-Al-Co3 Layered Double Hydroxide (LDH) via a facile solvothermal method using DMF (N,N’-Dimethylformamide) as solvent. The structure and morphology of the synthesized new materials have been investigated by X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) which confirmed obtaining MOF-ZnPA/LDH at different percentage of LDH (10, 30 and 50%). The adsorption characteristics of the synthesized materials for the Evans Blue dye showed an adsorption capacity of 246 mg/g for MOF-ZnPA/LDH compared to 141 mg/g for MOF-ZnPA without LDH after 40 minutes of contact time.
