Synthesis of Highly Mono-Dispersed Mesoporous Silica Spheres
Mono-dispersed mesoporous silica spheres with highly ordered hexagonal regularity were synthesized by hydrothermal method with tetraethoxysilane (TEOS) as silica source, cetyltrimethylammonium chloride (C16TAC) as template, methanol as co-solvent, and sodium hydroxide as alkali source. The influence of the C16TAC concentration, TEOS concentration, methanol/water ratio and the synthesis temperature on morphology and mesostructure of the prepared silica particles were investigated in detail. The results showed that the synthesized mono-dispersed spherical silica particles have ordered hexagonal mesoporous structure, high specific surface area and uniform pore size distribution.
