Biosynthesis of ZnO Nanoparticles from Aqueous Extract of Moringa Oleifera L.: Its Application as Antibacterial and Photocatalyst

ZnO nanoparticles were successfully synthesized by the biosynthesis method using water extract of Moringa leaf (Moringa oleifera L.) as a reducing agent and stabilizer well capping agent. This study aimed to characterize their application antibacterial photocatalyst. Characterization was carried out Fourier Transform Infrared (FT-IR) Spectroscopy X-Ray Diffraction (XRD).
