The present paper presents the synthesis and characterization of some new functionalized SBA-15 silica, by an improved synthesis route leading to well-organized mesoporous materials belonging to p6mm symmetry group. In a one-pot co-condensation synthesis we obtained and characterized SBA-APTMS and SBA-APTES samples.
Variation of the initial APTMS/TEOS and APTES/TEOS molar ratios and different TEOS pre-hydrolysis time were investigated. N2 sorption, FT-IR, NIR and XRD method were employed in determining the mesostructure characteristics of the obtained materials (SBA-15, SBA-APTMS x%, SBA-APTES x%, with x= 2, 4 and 8 % molar percent ).
