摘　　要：制备纳米颗粒主要采用w/o型微乳液,可分为单微乳液法和双微乳液法。本文对微乳液法制备纳米粉体粒度的主要影响因素如水核半径、反应物浓度、微乳液界面膜强度等进行讨论的基础上,对微乳液法制备纳米TiO2光催化剂常见微乳液体系进行了介绍,并讨论了制备过程中的一些影响因素,并提出了进一步的研究方向。The w/o microemulsification is mainly used in preparing nano-p ar ticles and used to be sorted single microemulsification and double microemulsifi cation.On the base of discussing the mainly effect factors,such as water-core radius,reactant concentration and microemulsification interfacial intensity,the common microemulsification systems used in preparing nano-sized titania photoc atalyst are introduced.Some effect factors in preparing program are discussed an d the further research direction is put forward also.
