In the present study, three compositions of W-doped titania nano-photocatalyst are synthesized via the sol-gel method. The powders obtained were characterized by X-ray diffraction, Raman spectroscopy and UV-visible diffuse reflectance spectroscopy. The photocatalytic performances of the different photocatalysts are tested with respect to the degradation of Diuron in water solutions under simulated solar light and visible light irradiation. The WTiO catalyst exhibits better photoactivity than the pure TiO even under simulated solar light and visible light. This improvement in activity was attributed to photoelectron/hole separation efficiency.
在本研究中，通过溶胶 - 凝胶法合成了三种W掺杂二氧化钛纳米光催化剂组合物。对所得粉末进行了X射线衍射、拉曼光谱和紫外 - 可见漫反射光谱表征。针对不同光催化剂在模拟太阳光和可见光照射下对水溶液中敌草隆的降解情况测试了其光催化性能。即使在模拟太阳光和可见光下，WTiO催化剂也比纯TiO表现出更好的光活性。活性的这种提高归因于光电子/空穴分离效率。
