Charging Effects on Bonding and Catalyzed Oxidation of CO on$Au_{8}$Clusters on MgO

Gold octamers ($Au_{8}$) bound to oxygen-vacancy F-center defects on Mg(001) are the smallest clusters to catalyze the low-temperature oxidation of CO to CO2, whereas clusters deposited on close-to-perfect magnesia surfaces remain chemically inert. Charging of the supported clusters plays a key role...
