Effect of phase composition on the formation of active sites in titania-ceria catalysts for ethyl acetate total oxidation

Popis výsledku v původním jazyce

The aim of current investigation is to elucidate the effect of phase composition of titanium-cerium mixed oxides on their textural, structural and surface properties. Nanosized mesoporous TiO2-CeO2 oxide materials were prepared by template-assisted hydrothermal synthesis using CTAB as a structure directing agent. The obtained samples were characterized by Nitrogen physisorption, X-ray diffraction, temperature-programmed reduction with hydrogen, UV-Vis, FTIR-and Raman spectroscopies. The catalytic activity of the obtained materials was tested in total oxidation of ethyl acetate as a representative member of hardly oxidized O-containing volatile organic compound (VOCs). All bi-component samples possess improved textural characteristics and redox properties due to the increased dispersion. All bi-component oxides demonstrate improved catalytic activity and selectivity in comparison with the mono-component materials in total oxidation of ethyl acetate. This could be a result of the improved textural characteristics and redox properties due to the increased particle dispersion.
