Isomorphous Substitution in Zeolites: A Route for the Preparation of Novel Catalysts

Abstract In the recent years a growing interest in the preparation, characterization and utilization of Titanium-silicalite has been observed. New interesting applications of TS-1, such as the low temperature oxidation of paraffins to alcohols and ketones, were reported. In this paper we will review the state of the knowledge concerned with the preparation of titanium-containing zeolites and the characterization of lattice Ti-sites. We will try to depict the emerging routes for research activities in this field.
