摘要：

The flower-like Bi2WO6 sample was successfully synthesized by a simple hydrothermal method without any surfactant. The crystal structure and morphology of the samples were characterized by XRD, SEM and BET technologies. The affecting factors on photocatalytic degradation Rhodamine-B (RhB) were investigated. The experimental results showed that the photocatalyst which processed highest photocatalytic activity was synthesized at 180°C for 12h; when the dosage of Bi2WO6 was 2g/L, irradiation time was 30min under 500W Xe lamp and the RhB concentration was 10mg/L with the originally pH of the solution, the degradation rate of RhB was up to 99.6%. The flower-like Bi2WO6 sample synthesized by a simple hydrothermal method had high photocatalytic activity.
