摘要
以溶胶-凝胶法制备纳米WO3/玻璃薄膜,并用UV-Vis法,IR法和XRD方法进行了表征。以10 mg/L罗丹明B为降解对象,考察其光催化性能。结果表明:经500℃灼烧2 h以上制备的厚度为278 nm的两层涂膜,在pH=3.0、鼓入空气、光强为1.81×1016光子/s等条件下薄膜具有最佳光催化活性,对罗丹明B的光催化降解效率在60 min内达到90%以上。
The nano-tungsten oxide（WO3）/glass thin film prepared by sol-gel method was investigated.The structure and photocatalytic behavior of the tungsten oxide（WO3） thin films was assessed by UV-Vis,XRD and IR.10 mg/L Rhodamine B solution was degradated on the thin film as an object of investigation.The removal ratio of Rhodamine B can reach 90% in 60 min under the condition that the media acidity was pH=3.0,air was plumped to the reactor through a gas pipe,and light intensity of 1.81×1016 photon/s.The two coating layer thin films were calcined at 500 ℃ for 2 h.
