摘要
将甲基橙溶液作为模拟废水,考察了热分解制备纳米TiO2后处理过程中采用硅油淬火改性和自然冷却所得产物的光催化活性。结果表明:两者均具有良好的光催化降解效果,且活性差别不大。但经硅油淬火改性的纳米TiO2因在水中具有强悬浮性,可更为有效地利用外部光源在工业废水的表层降解有害成分。
The photocatalytic activity of nano-TiO2 prepared by pyrolysis method and then by cooling-treatment in silicon oil and in air respectively was studied with methyl-orange solution as model waste water. The results show that the photocatalytic activity of both products is obvious with no great difference. However, the nano-TiO2 powder modified with silicone oil can degrade harmful components more effectively on the surface of waste water with sunlight and other extra light.
