A Facile Synthesis and Properties of Bismuth Vanadate (BiVO4) Photocatalyst by Hydrothermal Method

[摘要] In this study, BiVO4 photocatalysts were synthesized by hydrothermal method using Bi(NO3)3•5H2O and NH4VO3 as raw materials followed by calcination at different temperatures in the range from 350 °C to 600 °C. The as-synthesized BiVO4 samples were characterized by a number of physicochemical techniques including X-ray diffraction (XRD), Raman analysis, Scanning Electron Microscopy (SEM), and UV-Visible (UV-Vis) light diffuse reflectance spectrophotometry. The effect of temperatures calcination on structure, surface morphology, visible-light photocatalytic activity and light absorption performance of BiVO4 was discussed in details.
