采用Ｓｏｌ－Ｇｅｌ法制备ＷＯ３／ＴｉＯ２纳米粉末．以高压汞灯为光源，亚甲基蓝溶液的光催化降解为模型反应．结果表明：掺入ＷＯ３摩尔比为２％时，ＷＯ３／ＴｉＯ２的光活性最高；随着热处理温度升高，ＷＯ３／ＴｉＯ２光活性增强；ＷＯ３／ＴｉＯ２的Ｌａｎｇｍｕｉｒ动力学常数为０．０１０３６ｍｍｏｌ／（Ｌ·ｍｉｎ）－１；紫外－可见吸收光谱及离子色谱分析结果表明：与ＴｉＯ２相比，ＷＯ３／ＴｉＯ２为催化剂时亚甲基蓝分子的分解程度更高
Preparation of WO3 / TiO2 nanopowders by Sol-Gel method. Using high-pressure mercury lamp as a light source, the photocatalytic degradation of methylene blue solution is a model reaction. The results showed that the photocatalytic activity of WO3 / TiO2 was the highest when the molar ratio of WO3 was 2%, and the photoactivity of WO3 / TiO2 was enhanced with the increase of the temperature. The Langmuir kinetic constant of WO3 / TiO2 was 0.01036mmol / (L · Min -1). The results of UV-Vis absorption and ion chromatography indicated that the decomposition of methylene blue molecules was higher in WO3 / TiO2 catalyst than TiO2
