Preparation and characterization of vinyl-functionalized mesoporous SBA-15 silica by a direct synthesis method

Dynamic adsorption of volatile organic compounds on organofunctionalized SBA-15 materials

“…Increasing the amount of organosilane added in the initial synthesis mixtures caused a decrease in (1 1 0) for PTES/TEOS, respectively. However, the incorporation of MTES or PTES into the initial mixtures does not considerably disrupt the long-range mesoscopic order except a slight local disorder for the samples with larger concentrations of organosilanes, which is similar to the Wei's results [20].…”

“Clickable” SBA-15 mesoporous materials: synthesis, characterization and their reaction with alkynes

“…† These values are consistent with other organo-functionalized SBA-15 materials that have been reported before. [15][16][17]19 The FT-IR spectra of the various functionalized SBA-15 materials are presented in Fig. 4.…”

“…12,13 SBA-15 has been functionalized with various organic functional groups. These include amines, 14,15 thiols, 16 carboxylic acid, 17 sulfonic acid, 18 vinyl 19 and nitrogen based heterocycles. 9 In general, formulation of a siliceous SBA-15 with covalently linked functional groups can be designed using two different synthetic strategies for surface modification.…”

Adsorption and wetting characterization of hydrophobic SBA-15 silicas

“…Since this process was brought into focus [14,15] in 1996, the research in this area has been rapidly growing, for review see [16][17][18][19][20][21][22]. Preparation of SBA-15 through co-condensation of various hydrophobic silanes have been reported [23][24][25][26][27][28][29][30][31]. As compared to post-synthesis grafting, the direct synthesis approach is often credited with several advantages that include simplicity of the preparation, high organic loads, and homogeneous distribution of functionalities [16,18,19].…”
