Gold-rhodium and gold-molybdenum layers were prepared on a nearly stoichiometric titania and characterized by LEIS, XPS and STM. In the Au-Rh bimetallic system, Rh atoms impinged onto Au clusters pregrown on TiO 2(110) became covered by gold atoms. In contrast, Mo caused the disruption of gold nanoparticles.
