Aims: The aim of the study is to synthesize Zinc doped Bismuth oxide nanoparticles by simple precipitation method, their characteristics and to investigate the photocatalytic activity of these nanoparticles for Brilliant Green (BG) dye.
Study Design: Synthesis of Bi2O3
nanoparticles by precipitation method and photocatalysis of Brilliant green by
using Bi2O3 nanoparticles.
Place and Duration of Study: Department of Physics, School
of Applied Sciences, REVA University, Bangalore, between January 2024 to May
2024.
Methodology: The Zn/ Bi2O3nanoparticles
were synthesized by simple precipitation technique using Bismuth nitrate as
precursor. The synthesized Zn/ Bi2O3 nanoparticles were
studied for structural, optical, and morphological properties using X-ray diffraction
(XRD), ultraviolet-visible spectroscopy, scanning electron microscopy (SEM)
techniques. Dye degradation studies by UV source.
Results: XRD patterns were well matched with the JCPDS card
number 00-27-0050 with tetragonal structure with the crystallite size of 26.18
nm. The SEM analysis revealed the oxide particles to have spherical morphology.
The band gap of Bi2O3 nanoparticles was calculated using
Tauc’s plot and found to be 2.94 eV.
Conclusion: Zinc doped Bismuth oxide is a very good catalyst
and can be used for photodegradation of a dye and helpful in commercial
production of removal of such pollutants.
