摘　　要：以钛酸丁酯和六氯化钨为Ti源和W源,通过水热法制备了WO3/TiO2复合光催化材料,并采用XRD和XPS对其晶体结构、表面元素种类及化合价态进行表征。采用氙灯模拟可见光对活性艳蓝KN-R进行降解,考察了WO3的掺杂量、水热反应温度、反应时间、反应pH值以及煅烧温度和时间等对WO3/TiO2复合光催化剂光催化性能的影响。结果表明,WO3/TiO2物质的量比为15∶85、水热反应pH值为1、160℃反应6 h、500℃煅烧2 h的产物光催化活性最高,光照120 min后活性艳蓝KN-R的脱色率为92.33%。WO3/TiO2 composites are prepared by hydrothermal method using butyl titanate and tungsten hexachloride as Ti and W sources,respectively.The crystal structure,surface element and valence states of WO3/TiO2 are characterized by XRD and XPS.The photocatalytic experiments are conducted by degrading Reactive Brilliant Blue KN-R under visible light illumination.The effects of WO3 doping amounts,hydrothermal reaction temperature,reaction time,reaction pH value,calcination temperature and time on the photocatalytic performance of WO3/TiO2 composites are investigated in detail.The re⁃sults show that the WO3/TiO2 material ratio is 15∶85,the hydrothermal reaction pH value is 1,160℃re⁃acts for 6 h,and 500℃calcines for 2 h,the product has the highest photocatalytic activity.The decolor⁃ization rate of Reactive Brilliant Blue KN-R is 92.33%after illumination for 120 min.
