Effect of Water on Synthesis of Mesoporous Silica by Hydrolysis

Wang Haixia,Zhao Hui,Liu Shiquan(School of Materials Science and Engineering,University of Jinan, Jinan 250022,China)  
To investigate the influence of the amount of water on the synthesis of porous microspheres via hydrolysis,the porous silica microspheres were synthesized in the cetyltrimethylanmmonium bromide(CTAB)-tetraethyl orthosilicate(TEOS)-ammonia solution-water system with increasing water additions.The morphology and pore parameters of the silica microspheres were investigated.The results showed that the amount of water had influence on the size,dispersion,spheroidicity and pore parameters of the silica microspheres.When no water was added,the hydrolysis occured in the mixed solution of ammonia solution and ethanol.The microspheres were small in size,surface area and pore volume,and the silica microspheres were not well-defined in shape.With increasing the water additions,CTAB micelles formed in the water-ethanol solution acted as the template,with which the hydrolyzed silica assembled to form mesoporous silica microspheres.
