Milling Method

Orthorhombic Nb2WO8 was synthesized by solid state reaction in Nb2O5-WO3 system. Heterojunction photocatalyst Nb2WO8/ZnO was prepared by ball milling. The structural and optical properties of the photocatalyst were characterized by X-ray powder diffraction, transmission electron microscopy, UV–vis diffuse reflectance spectroscopy, and fluorescence emission spectroscopy.The photocatalytic activity was evaluated by photocatalytic oxidation of rhodamine B and reduction of Cr6+. The results showed that the photocatalytic activity of the Nb2WO8/ZnO was higher than that of ZnO. When the amount of doped Nb2WO8 was 10 wt.% and the sample was ball milled for 9 h, the Nb2WO8/ZnO showed the optimal photocatalytic activity. Effect of ball milling time on the photocatalytic activity was also investigated. The mechanisms of the increase in the photocatalytic activity were discussed by the valence band principle.

A novel Bi4O5Br2 ultrathin nanosheets material with 8 nm thickness was prepared via a reactable ionic liquids-assisted solvothermal method accompanied with facile pH control for the first time. The variable energy band structure of Bi4O5Br2 was responsible for the enhanced photocatalytic activity.
