Abstract:
A mesoporous metal silicate molecular sieve composition, wherein the metal is present in place of some of the silicon in the silicate and capable of undergoing a change of oxidation number in an oxidation or reduction reaction with an organic molecule having a kinetic diameter greater than 6 Ã¥, a scattering domain size of less than about 400 Ã¥, a ratio of textural to framework-confined mesoporosity of at least about 0.2 and a specific surface area of 300 to 1500 square meters per gram, which composition is prepared from a template consisting essentially of a neutral molecule and an inorganic oxide precursor and then the template is removed and has an x-ray diffraction pattern selected from the group consisting of FIGS. 2, 4, 10, 11 and 12.
