Model catalysts consisting of Au and Ag clusters of varying size have been prepared on single crystal TiO2 (110) and ultra-thin films of TiO2 , SiO2 and Al2 O3 . The morphology, electronic structure, and catalytic properties of these Au and Ag clusters have been investigated using low-energy ion scattering spectroscopy (LEIS), temperature-programmed desorption (TPD), X-ray photoelectron spectroscopy (XPS) and scanning tunneling microscopy (STM) and spectroscopy (STS) with emphasis on the unique properties of clusters
