Mesoporous Silica Platelets with Perpendicular Nanochannels via a Ternary Surfactant System

Mesoporous silica platelets with perpendicular nanochannels (see Figure) have been conveniently prepared by using a ternary cetyltrimethylammonium bromide–sodium dodecylsulfate–Pluronic123 surfactant system as a template and sodium silicate as the silica source. The diameter of the fabricated nanoch...

Zusammenfassung:Mesoporous silica platelets with perpendicular nanochannels (see Figure) have been conveniently prepared by using a ternary cetyltrimethylammonium bromide–sodium dodecylsulfate–Pluronic123 surfactant system as a template and sodium silicate as the silica source. The diameter of the fabricated nanochannels is about 7.0 nm, and the length distribution ranges from 30 to 100 nm.
