Ag/CeO2 catalysts were prepared by three different techniques (incipient impregnation, coprecipitation and impregnation of pre-reduced CeO2) and tested in oxidation of ethanol, total oxidation of CO and soot combustion. The features of Ag-CeO2 interaction were studied by TPR-H2, TEM HR, XPS and Raman methods. It was shown that the use of co-precipitation technique led to strong interaction between silver and ceria particles as well as to the epitaxy of silver particles (d111 = 2.35 Å) on the CeO2 surface (d111= 3.1 Å). Strengthening of metal–support interaction enhanced catalytic activity in CO oxidation, soot combustion and selective oxidation of ethanol to acetaldehyde.
