摘要
为得到易于回收的光催化材料,采用溶剂热法并结合冷冻干燥制备整体型Bi2WO6/石墨烯气凝胶,通过扫描电镜(SEM)、X射线衍射(XRD)、红外光谱(FT-IR)及紫外-可见漫反射光谱(UV-Vis)等方法对材料进行表征,探究不同水热温度对Bi2WO6/石墨烯气凝胶形貌、结构及性能的影响.结果表明,水热温度为120℃时材料整体性较好,110℃时光催化活性较好.在500 W氙灯照射下,光照120 min后对罗丹明B的降解率可达99.7%.
Abstract
In order to obtain the retrievable photocatalytic material,the monolithic Bi2WO6/gra-phene aerogel was successfully prepared by solvothermal method combined with freeze-drying.The materials were characterized by SEM,XRD,FT-IR and UV-Vis.The effects of different hy-drothermal temperatures on the morphology,structure and properties of Bi2WO6/graphene aer-ogel were investigated.The results show that when the hydrothermal temperature is 120℃,the material has good integrity;and when the hydrothermal temperature is 110℃,the material has good photocatalytic activity.The degradation rate of Rhodamine B can reach 99.7%after 120 min illumination with 500 W xenon lamp.
