%X Two different structures of mesoporous silica materials SBA-15 (P6mm) and SBA-16 (Im3m) were synthesized by using commercial block copolymers P123 and F127 as structure-directing agents correspondingly under acidic conditions. The characteristics of samples were investigated by using XRD, N2 adsorption-desorption, and HTEM techniques. The results show that the resulted mesoporous materials SBA-15 and SBA-16 are highly ordered materials. Their highest BET surface areas are respectively around 765m2·g-1 and 930m2·g-1. The pore diameters are 6.46nm and 3.92nm correspondingly. This means the synthesized mesoporous materials have potential applications in functional and economic materials.
