Abstract:

Firstly, we made the glucose as raw material to prepare carbon microspheres hydrothermal method. Then carbon microspheres use as a template, and Bi (NO₃)₃^.5H₂O and Na₂WO₄^.2H₂O as raw material to synthesize the Bi₂WO₆/carbon composite by refluxing method. Finally, Bi₂WO₆samples were obtained by calcination so as to remove the template. And samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and diffuse reflection absorption spectroscopy (DRS). The Rhodamine B (RhB) was simulated as the sewage under the visible light to study the impact of the illumination time, calcination temperature and the amount of catalyst. The results show that Bi₂WO₆ synthesized by calcination at 500 °C had the best photocatalytic performance, and when samples (30 mg) was put into RhB solution (10 mg/L) and illumination for 180 min, the degradation rate could reach 92%, which demonstrated that the samples exhibit excellent visible photocatalytic performance.
