Using sodium silicate as precursor, rod-like mesoporous silica with hexagonal appearance was synthesized by controlling the pH value of a mixed micelles solution of cetyltrimethylammonium bromide (CTAB) and cetyltrimethylammonium chloride (CTAC) during hydrolysis of ethyl acetate. The resulting mesoporous silica was characterized by small angle X-ray diffraction, nitrogen gas adsorption-desorption...
Using sodium silicate as precursors and mixed surfactants of cetyltrimethylammonium bromide (CTAB) and cetyltrimethylammonium chloride (CTAC) as templates, rod-like mesoporous silica with hexagonal appearance were synthesized by controlling the pH value of solution during hydrolysis of ethylacetate. Results showed that at a molar ratio of 9:1 (CTAB to CTAC), regular rod-like shapes were obtained,...
