Preparation of stable mesoporous silica FSM-16 from water glass in the presence of cetylpyridium bromide

The synthesis and characterization of the mesoporous materials FSM-16 (folded sheets mesoporous materials) with highly ordered structure in open-vessel by using cetylpyridium bromide (CPBr) and the single-layered polysilica Kanemite as new template and silicon source, respectively, has been investigated systematically. The hexagonal arrangements of uniformly size pores were characterized by FTIR, XRD, nitrogen adsorption, TG-DTA, SEM and TEM. Especially, the porous products with higher surface areas show remarkable thermal stability up to 1000°C. The potential application as carrier of catalysts or host-guest materials is anticipated.
