摘要：

A new method of incorporating TiO2 into zeolite cavities through ion exchange of zeolites Y with an aqueous solution of ammonium titanyl oxalate oxalate monohydrate, (NH4)2TiO(C2O4)2H2O, has been developed. Characterization of the products clearly demonstrates that (1) ion exchange between the Ti species present in the solution and the cations in the zeolities takes place; (2) the Ti species are located inside the zeolite cavities, but not on the external surface of the zeolite; and (3) the Ti-species encapsulated are TiO2 clusters of various small particles sizes and have characteristics of the TiO2 semiconductor.
