Synthesis and Characterization of a Novel Mixed-Ligand Zinc-Based Metal-Organic Framework

Metal-organic frameworks (MOFs) have been developed as inorganic materials alongside critical improvement within the few decades. MOFs incorporate a measured nature to permit extra flexibility, low density, astoundingly high surface area, and tunable pore functionality. This study focuses on determining the properties of novel zinc-based MOF with mixed linkers terephthalic acid (1,4-benzene dicarboxylic acid) and 1,10-phenanthroline through a straightforward solvothermal synthesis in the variation of mole ratios. Afterward, the Zn MOFs were characterized with FTIR, XRD, SEM-EDX, UV-Vis DRS, and Photoluminescence to determine their characteristics and properties. A bright yellow crystalline substance was obtained from different mole proportions metal to ligands. FT-IR data proposes that the zinc particle is bonded with the oxygen due to the characteristic peak within the Zn MOF C111 spectra observing the red-shifting. Sharp peaks on the XRD design indicate the Zn MOFs are crystalline materials with the crystallinity of 61.11 % for the Zn MOF C111. The SEM picture of Zn MOF C111 shows a porous layered structure with a semiconductor bandgap range, allowing electrons to be exchanged from the valence band to the conduction band with comparatively low energy. The photoluminescence curve displays an excitation peak at 401.89 nm upon emission with the maximum band at 521.25 nm. The physicochemical properties shows that the Zn MOFs are superbly potential for adsorption, photocatalytic, luminescence, and dye-degradation applications.
