45_18/2006Cover Picture: Changing the Activity of Electrocatalysts for Oxygen Reduction by Tuning the Surface Electronic Structure (Angew. Chem. Int. Ed. 18/2006)

Alloying platinum surfaces ... ... with 3d transition metals makes better cathodes for fuel cells. In their Communication on page 2897 ff., J. K. Nørskov and co-workers show that this process results in a tuning of the electronic structure of the surface and increases its catalytic activity for the oxygen reduction reaction. The cover picture shows how a wave function involving oxygen p and surface platinum d states in Pt3Co is influenced by cobalt atoms in the second layer.
