Photocatalytic Degradation Mechanism of the Visible-Light Responsive BiVO4/TiO2 Core–Shell Heterojunction Photocatalyst

The visible-light responsive BiVO4/TiO2 core–shell heterojunction photocatalyst was prepared by precipitation method. The crystal structure and optical properties of the samples were characterized. The XRD results indicated that the vector was anatase TiO2. EDS, XPS and XRD showed that BiVO4 was coated on the surface of TiO2. SPV and UV–Vis spectra certified that the BiVO4/TiO2 photocatalyst possessed better absorption in the visible-light...
