Zeolites and related micropoous materials hold a firm place in the field of industrial heterogeneous catalysis.  Often, the isomorphous substitutions of aluminum into the zeolite framework results in the formation of acid sites that are required for numerous conversions in refining and petrochemistry.  By isomorphous substitution of redox active transition metal elements into the framework of zeolite frameworks, a broad variety of �redox molecular sieves� can be obtained.  The latter, including well known examples such as Ti-containing silicalite-1 or Co- or Mn-containing AlPOs, were studied for numerous partial oxidation reactions and have, partly, already found their way into industrial application.  The current presentation highlights two examples for these combinations, i.e., (i) the novel manganese oxide-based octahedral molecular sieves for the aerial oxidation of benzyl alcohol to benzaldehyde and (ii) modified Ti-silicalite-1 catalysts for the epoxidation of fatty acid methyl esters as renewable feed-stocks for polymer production.
