Abstract Infrared reflection absorption and X-ray photoelectron spectroscopies are used to show that the process of carbon monoxide (CO) oxidation can occur on the surface of a system formed during the appearance of gold clusters on the surface of a titanium oxide layer cooled below room temperature. The efficiency of this process is significantly affected by stoichiometry of the titanium oxide layer. The use of a TiOx substrate with the stoichiometry different from TiO2 results in more effective CO oxidation in comparison with the process observed in the Au/TiO2 system. An important role in the oxidation process is played by the gold-oxide interface.
