Gold particles of 3 nm were deposited on Y-TiO2 and TiO2 supports. The incorporation of yttrium in TiO2 lattice favors the formation of oxygen vacancies. Au/Y-TiO2 catalysts showed higher activity and stability at RT than Au/TiO2, due to lower carbonate formation and to lower gold particle sintering during CO oxidation
