      摘要
    • 摘要: 用水热法ＳｉＯ２致密包覆封闭锐钛型ＴｉＯ２表面的光化学活性点，以Ｃｒ２Ｏ２－７的还原反应考察包覆层的致密性及包覆效果。讨论了ＴｉＯ２浆液的浓度、温度、ｐＨ及保温熟化等反应条件对ＳｉＯ２致密包覆的影响。

       

      Abstract: The hydrothermal surface modification with silica is applied to dense coat surface photochemical activity of anatase TiO2. The reducing reaction of Cr2O2-7 is used to evaluate the integrity of the coating layer, and TEM is used to inspect its surface state. Some factors, e.g., TiO2 slurry solid concentration, temperature, pH as well as reaction time, which dominate the dense coat were studied.
