| Abstract: | Bundle-like nanostructured SiO2 was quickly prepared by using cetyltrimethylammonium bromide(CTAB) as template and tetraethyl orthosilicate(TEOS) as precursor in aqueous/ethanolic solution.The morphology of the sample was characterized by transmission electron microscopy(TEM),and the influence of experiment parameters such as the content of the template and reaction time on the sample morphology was also discussed.In addition,the formation mechanism of bundle-like nanostructured SiO2 was proposed. |
