Water‐Gas Shift Reaction on a Highly Active Inverse CeOx/Cu(111) Catalyst: Unique Role of Ceria Nanoparticles

CeO takes charge: Ceria grows forming small islands on terraces (2–5 nm, CeOx-I) and large islands on steps of a copper substrate (30–50 nm, CeOx-II; see scheme; 100×100 nm2). The resulting CeOx/Cu(111) systems display an extraordinary water-gas shift activity and illustrate the role that an oxide can play in improving the performance of copper-based catalysts.
