Low‐coordinated gold atoms play a decisive role in the catalytic cycle of low‐temperature CO oxidation or the selective oxidation of olefins. A comparative study of argon and oxygen ion‐bombarded Au(111) surfaces (see microstructure images) reveals a threefold role of adsorbed oxygen: structure formation, stabilization of low‐coordinated gold atoms, and transfer during oxidation reactions.
