Abstract

Abstract: In this study, Bi2 O3 nanoparticles have been successfully synthesized using Jatropha multifida L. leaf extract (JMLE). Bi2 O3 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 Bi2 O3 have monoclinic structure, optical band gap of 3.34 eV, agglomerated morphology, and particle size of 17.26 nm. Photocatalytic activity of Bi2 O3 nanoparticles was investigated for the degradation of methylene blue (MB) under UV light irradiation with degradation percentage of 92.53 %.
