In recent years, nanotechnology has emerged as a start-of-the-art, with multifarious applications in a wide array of fields. Studies on green synthesis of nanoparticles moves forward these days. The present work involves the green method of synthesizing Iron oxide nanoparticles [Fe2O3] by Phyllanthus Niruri leaf extract and NaOH which acts as a precipitating agent. Furthermore, the green synthesized Iron oxide nanoparticles were characterized and its antibacterial activity was investigated. As this plant extract is more beneficial, it is energy efficient, low cost and environmentally friendly process than the biohazardous chemical synthesis. Iron oxide nano particles are gaining importance for their uses in environmental remediation technologies. The characterization of nano particles includes the IR, UV-Vis, and Size determination using SEM and XRD. The average crystalline size of the iron oxide nanoparticles was calculated by Debye’s Scherrer formula,d = 12.34nm. The analytical studies revealed that the synthesized Iron oxide nanoparticles almost have the identical size and morphology. Thus, the above studies concluded, the synthesized material was Iron oxide nanoparticles.
