| 英文摘要 | zwitterionic hybrid sba-15 mesoporous silica materials containing both amine and sulfonic acid groups have been synthesized through cocondensation from as-synthesized zwitterionic siloxane precursors (zs) with tetraethoxysilane (teos). characterization by xrd, tem, and n2 adsorptiondesorption measurements show that the as-synthesized materials have ordered mesostructures. analysis with uv, 29si/13c cross-polarization magic angle spinning (cp-mas) nmr, and x-ray photelectron spectroscopy (xps) and elemental analysis demonstrates that the zwitterionic parts have been successfully introduced into the silica framework, and the organic contents of 15?% hybrid samples are over 1.0 mmol/g. the presence of a secondary organoamine group enables the hybrid material to be further alkalized to achieve the desired basic properties. the materials were used as catalysts for the aldol condensation of acetone with 4-nitrobenzaldehyde. with a good catalytic performance, the catalyst could be easily separated, recycled, and reactivated by secondary basification. |
