Abstract
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 catalytic performance than traditional ones. This mini review summarizes recent progresses in developing the titanosilicates with novel topology, morphology as well as chemically modified micro-environment.
