Abstract
Metal–organic frameworks (MOFs) are intricate molecular solids formed by connecting organic ligands with metal or metal–cluster binding sites. They have exceptional characteristics such as expansive surface area, adaptability, and meticulously structured porosity, rendering them valuable in various applications including photocatalytic degradation and drug delivery systems. In this investigation, a benign Ni-based MOF was synthesized using benzene 1,4dicarboxylic acid as a linker and dimethyl sulfoxide as a solvent through the hydrothermal approach within a Teflon autoclave. The synthesized MOFs were precisely characterized using techniques such as X-ray diffraction, scanning electron microscope with energy-dispersive X-ray analysis, Fourier-transform infrared (FTIR) spectroscopy, thermogravimetric analysis, and N2-sorption measurements. The photocatalytic efficiency of the Ni-based MOF was explored against Congo red under visible light exposure, with the proposed mechanism involving electron transfer from photoexcited organic ligands to metallic clusters, resulting in a degradation efficiency of 98.68 % after 145 min. Furthermore, the Ni-based MOFs, when loaded with the anticancer drug cisplatin, displayed notable capabilities in drug delivery against the human breast cancer cell line MDA-MB-231, leading to a 35.26 % reduction in cell viability. Cytotoxicity assessments using the MTT assay revealed that the nano-carriers hindered cell proliferation with an IC50 value of 46.84 μg/mL.
