[Study of photocatalytic activity, characterization and preparation of supersuspended nano-TiO2 (II) photocatalytic activity].
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.
