Study on the Preparation of Dy-Doped TiO2 Nanotube Arrays and its Visible Light Responsive Photocatalytic Properties
The in-suit Dy-doped titanium dioxide nanotubes arrays were prepared by anodic oxidation method using Dy (NO3)3·6H2O and pure Ti sheet. The sample was characterized by SEM, XRD and XPS for its size and structure. The photocatalytic properties of nanotubes arrays were researched by using methyl orange as target degradation under the visible light. The results showed that the catalytic activity of Dy-doped titanium dioxide nanotubes arrays was 72% under visible light. The catalyst has hight stability and potential industrial applications.
