摘要

Bismuth vanadate (BiVO_(4)) nanoparticles were synthesized by a simple thermal decomposition method. The synthesized bismuth vanadate nanoparticles were characterized by X-ray diffraction analysis, it is found that the synthesized sample belongs to monoclinic BiVO_(4). Fourier transform infrared spectroscopy confirms the formation of Bi-O bond in the sample. Ultraviolet–Visible (DRS-UV–Visible) spectroscopy and photoluminescence spectroscopy reveal the optical property of the BiVO_(4) nanoparticles. The morphology was identified by both scanning electron microscopy and high-resolution transmission electron microscopy. Further, the photocatalytic activity of BiVO_(4) nanoparticles was investigated by photodegradation of methylene blue as a model organic pollutant.
