SBA-15 mesoporous molecular sieves are of regularly distributed pore sizes. Those with large pore sizes and thicker pore walls can be used as carrier materials and catalytic materials. However, SBA-15 surface is inert with an inactive center. After modifications, SBA-15 surface contains organic functional groups and acquires some new features, including regulation of the properties of mesoporous silica, such as hydrophilicity, hydrophobicity, as well as the connectivity and chemical reactions of guest molecules. In this paper, acryloyl cyclodextrin was synthesized with β- cyclodextrin and propylene chloride; SH-SBA-15 was obtained by thiolation of SBA-15 with sulfhydry. Finally, the desired product was obtained by combination of these two products. The final product was characterized with infrared spectroscopy.
Keywords: SBA-15; mesoporous molecular sieve; cyclodextrin; synthesis |
