Abstract: The supported metal/oxide systems consisting of Au and Ag metal clusters, deposited on the surface of TiOand MoO3 in high vacuum, have been studied by means of X-ray photoelectron spectroscopy and X-ray diffraction. The major feature for all the studied systems is the reduction of the oxide at the contact interface by the deposited metal. The minor details differentiating Au and, Ag as well as TiO2 and MoO3 are determined by the differences in electronic structure of Au and Ag, TiO2 and MoO3 , as well as their transformation at the contact.

Keywords: surface, border, interfacial oxide, metal, vacuum, diffraction, photoelectron spectroscopy, molybdenum, titanium, gold, silver
