Abstract
Abstract In this study, Bi 2 O 3 nanoparticles have been successfully synthesized using Jatropha multifida L. leaf extract (JMLE). Bi 2 O 3 nanoparticles were characterized by Fourier Transform Infrared (FT-IR) spectroscopy, X-Ray Diffraction (XRD), UV-Vis Diffuse Reflectance Spectroscopy (UV-Vis DRS), Scanning Electron Microscope-Energy Dispersive X-Ray (SEM-EDX) and Transmission Electron Microscope (TEM). These various characterizations were performed to analyze the functional groups, structural, optical, morphological, composition, and photocatalytic properties. The synthesized Bi 2 O 3 have monoclinic structure, optical band gap of 3.34 eV, agglomerated morphology, and particle size of 17.26 nm. Photocatalytic activity of Bi 2 O 3 nanoparticles was investigated for the degradation of methylene blue (MB) under UV light irradiation with degradation percentage of 92.53 %.
