dc.description.abstract | Titanosilicate MFI (a three-letter structural code among similar to 200 zeolite framework codes) nanosheets of single-unit-cell thickness were synthesized with a diquaternary ammonium surfactant as the zeolite structure-directing agent, that is, C(16)H(33)-N(+)(CH(3))(2)-C(6)H(12)-N(+)(CH(3))(2)-C(6)H(13). The resultant titanosilicate nanosheet possessed a large intersheet mesopore volume with high surface area due to the nanomorphic crystalline architecture as well as the isomorphically incorporated titanium species. Thus, it exhibited notable catalytic activities with high epoxide selectivity for bulky molecular epoxidation reactions using H(2)O(2) or t-butyl hydroperoxide as an oxidant. In addition, the catalytic performance could be enhanced via postsynthetic fluoride treatment with NH(4)F that can reduce the surface silanol groups and, hence, increase the surface hydrophobicity. | - |
