Interest in the composition and structure of submonolayer metal oxide deposits on metals has developed as a consequence of growing evidence that such deposits influence the adsorptive and catalytic properties of the substrate metal. In particular, it has been shown that titania deposited on a Ni(111) surface and on the surface of Pt and Rh foils will enhance the activity of the metal for CO hydrogenation. Similar results have also been reported for niobia deposited on a Pt foil. The present paper discusses the characterization of titania overlayers deposited on the surface of a polycrystalline Rh foil and a Rh(111) surface.
