AbstractIn this study, the Ag/CeO2 catalysts with three different morphologies of ceria nanocubes (CeO2-c), nanorods (CeO2-r) and nano-octahedra (CeO2-o) as supports were prepared by wet impregnation. Various characterizations such as XRD, BET, TEM/HRTEM, HAADF-STEM, XPS and H-2-TPR were conducted, and a four step catalytic transformation was accordingly proposed. It was found that Ag/CeO2-c showed much more metallic Ag, active oxygen species and higher reducibility than those of Ag/CeO2-r and Ag/CeO2-o mainly due to the morphology effect. Ag/CeO2 and CeO2 catalysts were evaluated in the oxidation of ethyl acetate, and their catalytic activities were in the sequence of Ag/CeO2-c > Ag/CeO2-r > CeO2-r > CeO2-c > Ag/CeO2-o > CeO2-o. Besides, in-situ FTIR results revealed that the organic species on the catalyst surface were mainly acetates and adsorbed ethyl acetate for Ag/CeO2-c and CeO2-c, respectively, suggesting that addition of Ag promoted the complete oxidation of ethyl acetate.
