Synthesis of isomorphically substituted Ru manganese molecular sieves and their catalytic properties for selective alcohol oxidation

[EN] Ruthenium has been incorporated into the framework of the cryptomelane type manganese oxide K-OMS-2 ([Ru]-K-OMS2) and the presence of this element into the structure has been assessed by combining analytical and vibrational techniques such as ICP, UV-Vis, FT-IR and Raman spectroscopies, X-ray diffraction, electron microscopy (HR-TEM and SEM), TPR-H-2, and X-ray photoelectron spectroscopy. Rietveld refinement of the X-ray diffractogram has allowed to estimate changes in the values of cell parameters which were compatible with an isomorphic ruthenium substitution into the original structure. These calculations are in agreement with the observed increase in the interplanar spacing of (100) planes from 7.1 angstrom to 7.7 angstrom for the Ru-doped material.Financial support by the European Union through ERC-AdG-2014-671093 (SynCatMatch), the Ministerio de Economia y Competitividad, Programa Severo Ochoa (SEV2016-0683) and Ministerio de Ciencia Innovacion y Universidades, Programa Estatal de Generacion de Conocimiento (PGC2018-101247-B-100) are gratefully acknowledged.
