Summary

A non-aqueous thermolytic method for the synthesis of highly homogeneous mixed-element oxides using well-defined oxygen-rich complexes based upon the OSi(OtBu)3 and O2P(OtBu)2 ligands is described. This method offers molecular-level control over the nanostructure of the resulting materials and allows for the tailoring of the properties of such materials. This thermolytic molecular precursor approach has been used to obtain high surface area and well-dispersed M/Si/O and M/P/O materials with a variety of transition and main group elements. This route often provides heterogeneous catalysts with properties that are superior to those of catalysts with the same composition, but prepared by traditional aqueous methods. The molecular precursors may be used to produce mesoporous materials with complex stoichiometrics and a homogeneous distribution of metal atoms within the walls via the use of templating agents. It has also been found that these molecular precursors may be used for the introduction of surface-bound and isolated catalytic species via simple grafting techniques.
