Synthesis of organo-functionalized mesoporous silica hollow nanospheres via in situ generated template method

Juan Wei, Yulong Li, Like Zou


A facile one-pot method has been developed for the synthesis of organo-functionalized mesoporous silica hollow nanospheres using TEOS, (R′O)3Si-R-Si(OR′)3 or R-Si(OR′)3 as silane precursors and CTAB as surfactant in ethanol–water/ammonia medium. The study shows that silica nanospheres formed by TEOS acts as in situ generated “soluble” template for the formation of hollow nanostructures. Different kinds of organic moieties such as –CH2CH2–, –C6H4–, –CH2C6H4CH2–, –CH2CH2CH2NHCH2CH2CH2–, –CH2CH2CH2NH2 could be successfully incorporated in the framework of hollow nanospheres.
