囊泡状介孔SiO_2合成因素的研究进展

Researching on the synthesis factors of vesicular mesoporous silica

讨论了利用不同类型的表面活性剂作模板,通过硅源的水解与凝聚反应得到不同孔径的囊泡状介孔SiO2的合成过程。综述了通过改变不同反应物(模板剂、硅源、助剂)及反应条件(温度、pH值)调控囊泡形成及介孔结构转变的相关机理,并对囊泡状介孔SiO2的应用和发展前景进行了展望。

The synthesized process of vesicle-like mesoporous Si02 with different pore sizes which can be prepared used various surfactants as templates and through hydrolysis and polymerization of silicon source in the appropriate condi- tions have been researched. The related mechanisms for controlling the formation of vesicle and the transformation of vesi- cle-like mesoporous structures by using various experimental materials including surfactant, silicon source, additives and changing experimental condition including temperature and pH have been reviewed. And the prospects of its application and development have also been predicted.
