Description: Ajt/CeOi cataljFsts with a sliver loedlnf; Ы I0«t.4 have been prepared Iqr three ditFerent techniques; imprej- luUoo, Ag/CeOi (Imp), Impregnation of prereduced СеОг, Ag/СеОз (red-tinp). and co-deposlttoa preclpltanon, AgOO-j (co-DP). The feaiuces of the prepared composites have heeo studied by km-temperature Nj urplion. TGA, ](RF, TPR-H2. ТЕМ HR. XPS and Raman tpecircecopy. The Raman and )(PS results show that the addition of silver to 00-, slgoificaiuly increases the defectiveness of CeO. particles, and such an effect is a function of the preparntlon method. The Ag-OO^ (co-DPI and Ag/CeOi (red-imp) catalysts show enhanced tnterfacial Ag-CeOi Intemction caused by the epitaxial growth of sliver particles (dm - 2.3S A) on the CeO- surface (d,,, - 3.1 A) as well as high amouni of oxygen vacancies. A motphology-depeodenl Interplay between the oxygen vacancies and the strength of the Ag-CeO^ Interaction has been revealed Strengthening of the metal-supporl Interaction enhances the catalytic activity of the composites in both (Ю oxidation and soot combustion.
