Synthesis of mesoporous silica using DTAB as an organic template

Abstract

Mesoporous silica was prepared by the hydrolysis of tetraethylorthosilicate (TEOS) in the presence of dodecyltrimethylammonium bromide (DTAB) as an organic template at room temperature. The shapes of synthesized products were greatly changed by the compositions of starting materials. The synthetic condition of spherical mesoporous silica using DTAB is severer than that using DDA.
