Synthesis of High Ordered Mesoporous Silica SBA-16 Within Columnar Alumina Pores

One-dimensional nano-scaled mesoporous silica was synthesized within anodic alumina membrane pores surfactant by Pluronic F127. In contrast to soaking the AAM into the precursor solution way, we use pressure-induced infiltration approach and it has advantages that mesoporous silica hardly forms on the surface of AAM. Nano-fiber with highly uniform structure was arranged along anodic alumina cavity. The hexagonal pore structure is visible on both fiber edges with the diameters of the pores being about 12 nm. The effects of the ratio of chemical reagent and the reaction time on the mesostructure was also investigated. The resulting hybrid mesoporous membrane could be used for enzyme catalytic and nanofluidic systems.
