Direct evidence for the instability and deactivation of mixed-oxide systems: influence of surface segregation and subsurface diffusion
In the current contribution, we provide a direct demonstration of the thermally induced surface structural transformations of an alkaline-earth oxide/transition metal oxide interface that is detrimental to the essential ...
Nature of the Ti-Ba interactions on the BaO/TiO2/Al 2O3 NOx storage system
A ternary oxide-based NO* storage material in the form of BaOZTiO2Zy-Al2O3 was synthesized and characterized. Thermally induced structural changes occurring on the surfaces of the TiO2Zy-Al2O3 and BaOZ TiO 2Zy-Al2O3 systems ...
