Fabrication of mesoporous silica nanofibers using dual structure-directing agents and their catalytic application |
| 초록 |
Mesoporous silica nanofibers(MSNFs) were fabricated using dual structure-directing agents in the pores of porous alumina template (AAO). The mesostructure of the MSNFs could be controlled by composition of two structure-directing agents, such as pluronic and cationic surfactants. Vapor phase synthesis were used to introduce the silica precursor in the pore of AAO. Furthermore, solid-state basic catalysts were prepared by anchoring an amino silane on the surface of mesoporous nanofibers. The amino-group-functionalized MSNFs with cylindrical mesopores exhibited over 90% of conversion yield, near 100% of selectivity and could be used as an effective heterogeneous basic catalyst. |
