FeliuTag der Promotion: 21.Oktober 2010Für Philipp,Santina und RasmusPrefaceIn recent years, planar model catalysts have been increasingly employed for de-tailed mechanistic studies of catalytic and electrocatalytic processes, exploiting thewell-defined structure as well as electronic and chemical properties of these modelsystems. Recent developments in Nanotechnology have provided new opportuni-ties for the fabrication of, e.g., well-defined nanostructured planar Pt/glassy carbon(GC) model electrodes with essentially monodisperse particle sizes and/or regularparticle separations. Model catalysts have so far mainly been employed in studiesof heterogeneously catalyzed reactions at the solid-gas interface, whereas studies ofelectrocatalytic reactions are sparse.
