Cover Picture: Opposite Face Sensitivity of CeO2 in Hydrogenation and Oxidation Catalysis (Angew. Chem. Int. Ed. 45/2014).

Structure–performance relationshipsof ceria in heterogeneous reactions are revealed by J. Pérez‐Ramírez, A. Trovarelli, et al. in their Communication on page 12069 ff. The (111) surface prevalent in conventional polyhedral CeO2 particles outperforms in hydrogenation, while the (100) surface that is exposed in nanocubes dominates in oxidation.
