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。

Abstract: The w/o microemulsification is mainly used in preparingnano-particles and used to be sorted single microemulsification and doublemicroemulsification. On the base of discussing the mainly effect factors, suchas water - core radius, reactant concentration and microemulsification inter-facial intensity, the common microemulsification systems used in preparingnano-sized titania photocatalyst are introduced. Some effect factors inpreparing program are discussed and the further research direction is put for-ward also.
