Abstract: The process of carbon monoxide (CO) oxidation on the surface of a system comprising nanodimensional gold clusters deposited onto thin films of titanium oxide of variable stoichiometry formed on a Re(1000) single crystal surface has been studied by methods of thermodesorption, IR, and X-ray photoelectron spectroscopy. It is established that oxygen contained in titanium oxide plays an important role in the conversion of CO into CO$_2$. The efficiency of this process on the Au/TiO$_x$ ($x <$ 2) system surface is significantly higher that that on the Au/TiO$_2$ system.
