ABSTRACT

The electronic, structural, and chemical properties of unsupported metal and mixed-metal surfaces prepared either as single crystals or thin films have been detailed and contrasted with the corresponding properties of supported metal [1,2] and mixed-metal nanoclusters [3,4]. The latter vary in size from a few atoms to many and have been prepared on ultrathin single crystalline oxide supports of TiO2, Al2O3, and SiO2. An array of surface techniques including reaction kinetics of carbon monoxide oxidation and vinyl acetate synthesis have been used to correlate catalytic function of these surfaces with their physical and electronic properties. Of special interest are the special physical and chemical properties that develop with metal cluster size reduction and/or metal-support interaction. Recent STM studies of mixed-metal catalysts prepared by alloying Pd with Au will be highlighted [5,6].
