摘　　要：Titanosilicates, with tetrahedrally coordinated Ti4＋ ions in highly crystalline zeolite frameworks, are a class of unique heterogeneous catalysts useful for the liquid-phase selective oxidation reactions. The great success of green Ti-zeolites/H2O2 reaction system has aroused considerable scientific and industrial interests. The catalytic properties of titanosilicates relay on zeolite topologies, crystal morphology, the content and micro-environment of tetrahedral Ti4＋ ions. The ever-growing needs for the oxidation catalysts in processing bulky molecules in petrochemical and fine chemical industries have set off a new tide of developing novel titanosilicates with significantly improved cat- alytic performance than traditional ones. This mini review summarizes recent progresses in developing the titano- silicates with novel topology, morphology as well as chemically modified micro-environment.Titanosilicates, with tetrahedrally coordinated Ti4＋ ions in highly crystalline zeolite frameworks, are a class of unique heterogeneous catalysts useful for the liquid-phase selective oxidation reactions.
