Abstract: A hybrid mesoporous HMS silica materials were synthesized via co-condensation between tetraethylorthosilicate(TEOS) and bis[3-(trimethoxysilyl)propyl]amine(BTMSPA) by using octadecylamine as the template through the “S0I0” route. The sequential addition of TEOS and BTMSPA resulted in well-ordered porous hybrid silicates. The synthesized materials were characterized by means of X-ray diffraction, N2 gas adsorption-desorption experiments, 29Si MAS NMR and condensation reaction of benzaldehyde with 2'-hydroxyacetopheone.

Key words: Mesopore, Hybrid material, HMS mesopore material, Basic catalysis
