1. Organized mesoporous silicas
1.1 Arrangements
Organized mesoporous silicas are inorganic materials obtained by a sol-gel process in the presence of a surfactant (cationic, neutral or anionic), giving rise to a periodic organization of the amorphous inorganic matrix around ordered organic mesophases. . The driving force leading to this organization is the condensation of inorganic precursors (e.g. tetraethoxysilane, TEOS) in interaction with surfactant micelles (e.g. cetyltrimethylammonium bromide, CTAB).
For the same silicic precursor and surfactant,...
