In this study, nickel oxide nanoparticles (NiO NPs) were synthesized using Lantana camara flower extracts. Electrochemical (EIS and PDP) are conducted on the synthesized NiO NPs nanoparticles to show the corrosion inhibition efficiency. An XRD analysis showed that NiO-NPs generated a FCC structure that exhibited single-crystalline properties. SEM images showed particle size to be between 40 and 50 nm, which matched the average size determined from the XRD pattern. As compared to the reported spectrum, Fourier-transform infrared spectroscopy confirms the formation of NiO-NPs. A degradation study of Methylene blue (MB dye) photocatalytically showed up to 96–98%. Furthermore, the study reveals NiO-NPs possess antimicrobial activity against Escherichia coli, Staphylococcus aureus, and Micrococcus luteus. These nanoparticles were made in a sustainable and cost-efficient manner. The research paves the way for future developments in the fields of biomedical applications.
