Can't keep me down : Silver nanoclusters (NCs), formed by spontaneous atomic‐level dispersion of non‐nano silver onto Al 2 O 3 surface, show self‐ regenerative properties during redox aging above 900 °C and, consequently, higher activity than state‐of‐the‐art CO oxidation catalysts after the aging. Size‐dependence of the activity and DFT calculation indicate that Ag atoms at corner/edge sites are the active site of Ag NCs.
