- Аннотация: Rhenium and molybdenum oxide clusters were synthesized from the Re 2O3(OMe)6, ReMoO2(MeO)7, and Mo2O2(OMe)8 oxomethoxide complexes. The nanomaterials obtained were studied by the FTIR, DTA, EXAFS, and H 2-TPR techniques. It was established that, in microporous NaY zeolite, the oxomethoxide complexes lose their ligands, so that only metal suboxide cores penetrate into the intracrystalline space, where they reside as nanosized clusters. It was found that the reduction of the clusters depends strongly on their size and the location in the matrix. The matrix environment also affects the transitions between different oxidation states of Re and Mo and the degree of reduction of their oxides.
