The Nickel Oxide (NiO) nanoparticles are synthesized using the green synthesis method utilizing Brassica oleracea L. var. capitata leaf extracts. The X-ray diffraction studies revealed that synthesized NiO-NPs exhibit face-centered cubic structure. SEM images of NiO-NPs exhibited agglomerated structures. TEM images of NiO-NPs revealed spherical morphology with variable sizes ranging from 5-50 nm. FT-IR spectrum was used to confirm the various functional groups. The absorbance spectral studies reveal the existence of three important peaks at wavelength 545 nm, 589 nm, and 636 nm. The antibacterial activity of NiO-NPs against Gram +ve Staphylococcus aureus (NCIM2079), Bacillus subtilis (NCIM2250), and Gram –ve Pseudomonas aeruginosa (MTCC3541), Escherichia coli (NCIM2065) was further studied. The anticancer activity of NiO-NPs against lung cancer cells (NRU-A549) was examined. The IC50 value was found to be 326.4 µg/mL. The synthesized NiO-NPs were further studied for electrochemical and supercapacitor applications.
