Eco-Friendly Green Synthesis, Characterizations, and Antimicrobial Activities of Nickel Oxide Nanoparticles

Abstract

The simple solution combustion method has been used for the synthesis of NiO nanoparticles using nickel nitrate as an oxidizer, Samanea saman pod extract as a fuel at 500°C. The crystalline nature of the nanoparticles was confirmed by X-ray diffraction studies and SEM images the information about surface morphology of the nickel oxide. The EDS spectrum confirms the composition and purity of the nanoparticles. Further, the nanoparticles are subjected for antimicrobial activity. The results revealed that NiO nanoparticles exhibit good antimicrobial properties.
