Topic of this workshop

CeO2-based materials exhibit excellent material storage properties that are beneficial in e.g. the heterogeneous catalysis and as oxygen ion conductor in high temperature solid oxide fuel cells. Storage properties are inherently deter-mined by the bulk material, while catalytic properties are surface dominated processes. Therefore the tailored interplay between bulk and surface properties is at the heart of catalytic applications of CeO2-based materials.

 

Unfortunately, there is an insufficient exchange of knowledge and concepts among the scientific communities “bulk versus surface” respectively “electrochemistry versus hetero-geneous catalysis”. This workshop should help to overcome this apparent “community gap” and open our minds for new applications.

 

Nanostructuring of CeO2-based materials is a modern synthesis concept to intensify the interplay between bulk- and surface defect properties. If CeO2 is however used as a carrier for the active metal particles, then the complex redox chemistry between the metal particle and the substrate may affect the catalytic performance. Ab initio theory helps to unravel the complex interaction between bulk and surface properties as well the supported metal particles and the substrate.
