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

In this work, ZnO nanoparticles were synthesized via a simple green method using just plant extract. The synthesized ZnO nanoparticles were characterized using 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). Photocatalytic activities of the ZnO nanoparticles were evaluated by degradation of methylene blue under UV radiation. Moreover, the antibacterial activity of the synthesized ZnO nanoparticles against S. aureus, S. paratyphi, V. cholerae, and E. coli were screened.
