| 摘 要： | 以TiCl4,有机羧酸等为主要原料,首先采用常温络合-控制水解技术制备出锶掺杂纳米TiO2无色透明水溶胶,然后使用0.5 mm口径的喷枪,在0.8 MPa压力下,利用普通喷涂技术将所制备的透明溶胶均匀的喷涂在玻璃表面或者烧杯内壁,得到了均匀透明的纳米薄膜。以酸性红3R染料溶液模拟染料废水,研究了锶掺杂纳米TiO2薄膜的光催化性能,同时探讨了体系pH,光照时间以及染料初始浓度对光催化效果的影响。

| Abstract: | The Sr-doped transparent and colorless TiO2 hydrosol was prepared by normal temperature complexation combined with hydrolysis controlled technology by using TiCl4 and organic acids as main raw materials. Subsquently, the uniform transparent nano-film was obtained by common spraying technology by spreading the as-synthesized TiO2 hydrosol on the surface of the glass or beaker with spray gun (0.5 mm) under pressure of 0.8 Mpa. The photocatalytic properties of nanosized Sr-doped TiO2 film were studied with acid red 3R as waste water, and the effect of pH, illumination time, and initial concentration of dye on catalytic performance were also investigated in detail. |
