Synthesis and Characterization of Bi2O3 NPS and Photocatalytic Application with Methylene Blue

Abstract

Nanoparticles of bismuth oxide were successfully synthesized by hydrothermal process which included Bismuth (III) nitrate (Bi(NO3)3.6H2O), sodium hydroxide(NaOH) and Nitric acid(HNO3) without further purification along with ultra-pure water. To investigate the structural, optical, and photocatalytic activity of two samples (1:5) and (1:6) respectively with two different NaOH precipitating agent molar ratios. The prepared nanoparticles were characterized by X-ray diffraction (XRD), UV-Vis’s spectrometer, scanning electron microscope (SEM), Energy-dispersive X-ray spectroscopy (EDAX), Fourier transform infrared spectroscopy (FTIR) and X-ray Photo electron Spectroscopy (XPS). Based on the obtained results the hydrothermally synthesized Bi2O3 NPs exhibit good efficiency to photocatalytic degradation of Methylene blue under the irradiation of LED white light.

Enhanced Growth of Green Synthesized Bi2Fe4O9: Nanoparticles Decorated on MWCNT

“…The XRD crystallographic data, which clearly clarified the consideration of alternative association of the phytocompounds agrees with our proposed mechanism, and the strong observation of the UV-band and FTIR peaks at 200 nm and 462 nm, respectively, agree to the Bi and Fe observed for this sample. Due to the strong electrostatic interaction between the positively charged ions and the negatively charged cytoplasmic membrane of the bacteria, more Bi 2+ and Fe 2+ ions are released from the surface of the nanopowder, which causes the bacterium colony to vanish 28 .…”
