Physicochemical characterization of Au/CeO2 solid. Part 1: The deposition-precipitation preparation method

► Au/CeO2 solid prepared by the deposition-precipitation method presents highly dispersed Au nanoparticles. ► The adsorption on Au/CeO2 of NO, NO2, N2O and O2 leads to the formation of O2−. ► The adsorption of CO on Au/CeO2 leads to the formation of CO2−. ► The adsorption of 17O2 on Au/CeO2 shows that the two adsorbed oxygen are equivalent.
