Insights into the biogenic production of nanocomposites of NiO-chitosan for wastewater remediation.

In our study, we have tried to enhance the biological qualities of nickel oxide nanoparticles and nanocomposites which were prepared using the extract of Aegle marmelos tree leaves and chitosan biopolymer. For in-depth study of the fabricated samples, numerous physiochemical approaches were utilized. The analysis used consists of field emission scanning electron microscopy with energy dispersive X-ray analysis and photoluminescence, X-ray diffraction, UV-visible spectroscopy, and Fourier transform infrared spectroscopy. The crystallite size was measured to be about 9.36 nm and 39.5 nm for Ni-nanoparticles and Ni-nanocomposite respectively. Both, the Ni-nanoparticles and Ni-nanocomposites demonstrated effective antifungal properties toward the fungus strain of Sclerotinia sclerotiorum. The samples showed the strongest antifungal efficacy against Sclerotinia sclerotiorum at doses of 100 and 150 mg. The prepared samples also showed good photocatalytic degradation efficiencies for the commercial Rhodamine B dye. The synergistic features that have been found indicate that these bio-functionalized NiO-chitosan NCs may be suitable for the treatment of industrial wastewater and biomedical applications.
