Synthesis and characterization of Bi2O3 NPS and photocatalytic application with methylene blue

Bismuth oxide nanoparticle was synthesized by Hydrothermal method, with two different molar ratio of precipitating agent NaOH which decided the variations samples (1:5) and (1:6) added to observe its effect on structural, optical photocatalytic behaviour. So prepared bismuth nano particle characterized X-ray Diffractometer study about crystalline properties. The crystal size observed as 30.7 42.84 nm, properties were using UV-Vis spectrometer band gap value calculated 2.74 eV 2.42 respectively. Morphological studies obtained scanning electron microscopy elemental analysis confirmed proportions Bi2O3 nanoparticles (1:6). FTIR Spectrometer explained condensation OH group accompanied formation is strongly dependent pH reaction. A lattice change observed, symmetric asymmetric bonds analysed spectrometer. binding energy level Photo Spectroscopy 292 534 eV, also hydrothermal synthesised NPs used degradation Methylene blue under irradiation LED white light.
