摘要

In this study, Zinc and benzenedicarboxlyate (BDC) linkers-based MOF-5 was synthesized via novel condensation approach under refluxing condition and thoroughly characterized to evaluate its structural, morphological, electrical, and optical properties. The synthesised MOF-5 was systematically characterized using power X-ray diffraction (PXRD) for phase identification, field emission scanning electron microscopy (FESEM) coupled with energy dispersive X-ray spectroscopy (EDS) for morphological and elemental analysis, Fourier –transform infrared spectroscopy for functional group identification, Ultraviolet-visible (UV–vis) absorption spectroscopy, photoluminescence spectroscopy, raman spectroscopy for optical characterization and Brunauer–Emmett–Teller (BET) analysis for evaluating the specific surface area and pore characteristics. The crystallite size was further estimated through Debye–Scherrer equation from PXRD pattern. The estimated crystallite sizes were 94.93, 40.21, 39.52 and 46.13 nm corresponding to the (200), (110), (002), and (−111) lattice planes respectively with an average crystallite size i.e. 55.21 nm. XRD patterns confirmed the high crystallinity of the synthesized material, while SEM images revealed a rectangular, plate-like morphology within the microscale range, with slight aggregation, both influenced by the synthesis conditions. BET analysis shows that MOF-5 possesses a moderate specific surface area of 10.080 m2/g, with a total pore volume of 0.029 cc/g and an average pore radius of 21.395 Å measured at 77.35 K.
