Emblica officinalis leaf extract mediated synthesis of zinc oxide nanoparticles for antibacterial and photocatalytic activities

ZnO nanoparticles have been synthesized via a simple green method using plant extract without the use of any other chemicals. The synthesized ZnO nanoparticles were characterized by UV–vis diffuse reflectance spectroscopy (UV-vis DRS), photoluminescence measurements (PL), X-ray diffraction (XRD), fourier transform infrared spectroscopy (FT-IR), field emission-scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM), respectively. Photocatalytic activities of ZnO nanoparticles were evaluated by degradation of methylene blue under UV radiation. Moreover, the antibacterial activity of synthesized ZnO nanoparticles against S. aureus, S. paratyphi, V. cholerae, and E. coli are also screened.
