Bi2WO6 催化剂的制备及其光催化活性研究
首发时间:2018-05-28
摘要:采用水热合成法制备Bi2WO6,通过XRD、SEM等手段对不同条件下制备的催化剂Bi2WO6进行表征,并在可见光照射下,考察Bi2WO6催化剂降解苯酚(20 ppm)的光催化性能。结果表明:条件不同,催化剂Bi2WO6的光催化性能有很大的影响,12 h、180℃、PVP下光催化性能最好。因为温度12 h,温度180℃,表面活性剂 PVP时,催化剂的微观结构最好,形貌最稳定,催化剂对苯酚降解率最高,为23.66%。

Preparation and photocatalytic activity of Bi2WO6
Abstract:Bi2WO6 was synthesized by a hydrothermal route. The samples were characterized by XRD,SEM. The photocatalytic performance of the Bi2WO6 catalyst was evaluated by the photocatalytic decomposition of phenol (20 ppm) under visible light irradiation. The results show that the photocatalytic performance of the catalyst Bi2WO6 has great influence on the conditions, and the best photocatalytic performance is obtained at 12 h, 180 C, and PVP. Because of the temperature of 12 h, the temperature of 180 C, and the surfactant PVP, the microstructure of the catalyst is the best and the morphology is the most stable. The degradation rate of the catalyst to phenol is the highest, which is 23.66%.
