Abstract

Abstract: Mesoporous silica nano-particles （MSN） were synthesized using different experimental methods, respectively. The result of zize analysis showed that using NaOH as pH adjusting agent, a suitable proportion of ethanol and water as solvent, in certain conditions prepared the MSN particle, which has relatively uniform and concentrated particle size distribution, between 200 nm to 300 nm. The preferred sample prepared in this way, used hydrochloric acid or calcined to romove template CTAB, and then grafted -NH₂ on its surface, to obtain amino-functionalized medium mesoporous silica. The TGA, FTIR were used to characterize the product.

Key words: mesoporous silica, amino-functionalizing, APTES
