研究以四异丙醇钛 [Ti (iso OC3 H7) 4 ]、硅酸乙酯为原料 ,以空心玻璃微球为载体 ,用溶胶 凝胶法制备可漂浮附载型复合光催化剂TiO2 ·SiO2 /beads的过程 ,利用附载型复合光催化剂降解有机磷农药。结果表明 :附载型复合光催化剂活性显著提高 ,牢固性增强 ,TiO2 ·SiO2 摩尔比存在最佳值。n (TiO2 ) /m (SiO2 ) =30 / 70时 ,光催化剂活性最高 ,其活性是同样降解条件下 ,同样含量DegussaP 2 5TiO2 的 2倍左右
In this paper, TiO2 · SiO2 / beads (TiO2 · SiO2 / beads) which can be supported on float glass are prepared by sol-gel method using titanium tetraisopropoxide [Ti (iso OC3 H7) 4] and ethyl silicate as raw materials and hollow glass microspheres The use of supported photocatalyst degradation of organophosphorus pesticides. The results showed that the photocatalytic activity of supported composite photocatalyst was significantly improved, and its solidity was enhanced. The molar ratio of TiO2 · SiO2 was the best. n (TiO2) / m (SiO2) = 30/70, the highest photocatalytic activity, its activity is the same degradation conditions, the same content of DegussaP 2 5TiO2 about 2 times
