摘要: Here, the development of ordered mesoporous silica prepared by reaction layered silicates with organoammonium surfactants is reviewed. The specific features are discussed relation to probable formation mechanisms. recent understanding unusual structural changes from 2D structure periodic 3D mesostructures presented. mesophase single silicate sheets depends on combined factors including reactivity silicates, presence intermediates, variation sheets, and assemblies surfactant molecules in interlayer spaces. FSM-16-type (p6mm) formed via intermediates composed fragmented alkyltrimethylammonium (C n TMA) cations. KSW-2-type (c2mm) can be through bending individual intralayer condensation. Although during reactions C TMA cations a complex manner, units caused kanemite frameworks retained. Recent design framework very important for obtaining KSW-2-based molecularly frameworks. originating chemically designed structurally stabilized direct silylation as-synthesized KSW-2. Some proposed applications using these also summarized some remarks uniqueness use comparison MCM-type silica.
