Catalytic CO Oxidation by a Gold Nanoparticle: A Density Functional Study
摘要：
Gold is usually considered very noble. It does not oxidize, and the surface of gold cannot adsorb most molecules from the gas phase. Yet it has been found that nanometer size gold particles on different oxide supports can act as catalysts even at or below room temperature. We present self-consistent density functional calculations showing that even an isolated Au10 cluster should be able to catalyze the CO oxidation reaction even below room temperature. We use the calculations to analyze the origin of this effect and suggest that the extraordinary reactivity can be traced back to special reaction geometries available at small particles in combination with an enhanced ability of low coordinated gold atoms to interact with molecules from the surroundings.
