| 摘要 |
The invention discloses three-dimensional, ordered, mesoporous titanosilicates wherein the Ti is in a tetrahedral geometry and exclusively substituted for Si in the silica framework. Such titanosilicates find use as catalysts for epoxidation, hydroxylation, C-H bond oxidation, oxidation of sulfides, aminolysis of epoxide and amoximation, with approx. 100% selectivity towards the products.
