Abstract

Highly ordered hexagonal mesoporous silica SBA-15 with tunable morphology such as donut-like has been synthesized through the cosolvent approach. Donut-like SBA-15 prepared by using DMF cosolvent shows highly ordered circle channels and large mesopore size of 9. 9 nm and pore volume of 1. 45 cm3/g. Cosurfactant approach has also been used to control the morphology of SBA-15, resulting that highly ordered hard spheres (uniformed diameter - 800 nm) mesoporous silica are formed. The morphology of mesoporous SBA-15 is much depended on the surface curvature energy of interface of inorganic silica and organic block copolymer species.
