摘要
讨论了通过光化学反应在水介质中由Ｔｉ３＋离子制备纳米ＴｉＯ２微胶粒（１５～２５ｎｍ）的实验方法；研究了光化学反应条件（温度、浓度、酸度等）对反应速率的影响；探讨了纳米ＴｉＯ２微胶粒的量子尺寸效应、电性及聚沉、稳定存在条件及光催化活性等性能．为研制超细ＴｉＯ２微胶粒子提供了实验方法和理论依据．
Nanometre TiO 2 micromicellae are prepared from Ti 3+ ion in an aqueous medium by photo chemistry reaction.Its size is in the range of 15～25 nm.The effects of the photo chemistry reaction,such as temperature,condensation of Ti 3+ ions and acidity,on the ratio of reaction are investigated.The quamtum size effect,electricity,coagulation,stability and photo catalytic activity of the prepared nanometre TiO 2 micromicellae are also discussed.This paper provides an experimental method and a theoretical basis for the preparation of super fine TiO 2 micromicellae.
