Zusammenfassung
V2O5 dispersed on high surface area metal oxides, such as SiO2, Al2O3, TiO2, or ZrO2, has been the topic of many experimental and theoretical approaches targeted at a deeper understanding of heterogeneous oxidation catalysis on a molecular level.1 Structure, reactivity and stability of the active, two-dimensional vanadium oxide surface species depend on catalyst synthesis, nature of the support and reaction conditions. In the present work, highly dispersed VxOy supported on mesoporous silica (SBA-15) modified with titania has been used as a model system to investigate the vanadia-support interaction and the effect of the degree of aggregation of vanadium oxo-species on the reactivity in oxidative dehydrogenation (ODH) of propane applying in-situ spectroscopic techniques.
