Abstract:
The interaction of silver with the surface of CeO2 in the Ag/CeO2 catalysts prepared by coprecipitation
and impregnation techniques was studied by temperature-programmed reduction, X-ray diffraction,
and high-resolution transmission electron microscopy. It was shown that coprecipitation technique led to
formation of strong silver–support interaction and the epitaxy of silver particles (d111 = 2.35 Å) on the surface
of CeO2 (d111 = 3.1 Å). This provided incresed catalytic activity in the oxidative dehydrogenation of ethanol
at relatively low temperatures (a 15% conversion of ethanol with 100% selectivity for the formation of acetaldehyde
was reached at 85°C). Above 130°C, the deep oxidation of ethanol to CO2 becomes the predominant
direction of a catalytic reaction, and the Ag/CеО2 catalyst obtained by impregnation technique was most
active in this region as a consequence of the weaker metal–support interaction.
