摘要

A semiconductor-based Cu-doped Bi_2WO_6 photocatalyst was synthesized successfully via the hydrothermal method. As-prepared samples were characterized by XRD, UV-vis DRS, SEM, and specific surface area. Results revealed that Cu-Bi_2WO_6 presented a structure of porous microspheres and a nanosheet as well as a crystal structure of orthorhombic phase. Photocatalytic properties were evaluated by degrading phenol-containing wastewater under visible light irradiation. Results showed that Cu- Bi_2WO_6 can display a more improved photocatalytic oxidative ability than pure Bi_2WO_6. Furthermore, the possible mechanism of photocatalysis has been addressed.
