TL;DR: In this article, a series of ceria-containing mixed oxides has been prepared and utilized as catalysts in the oxidation of acetic acid in water, and the best results are obtained with the ternary mixed-oxides CeO 2 -ZrO 2 −CuO and CeO2 -MnO x which benefit from a synergetic interaction between the two materials.
Abstract: A series of ceria-containing mixed oxides has been prepared and utilized as catalysts in the oxidation of acetic acid in water. The incorporation of even relatively small amounts of ZrO 2 and MnO x or CuO into the fluorite lattice of CeO 2 strongly enhances the redox properties of the material with a consequent promotion of the oxidation activity. The best results are obtained with the ternary mixed-oxides CeO 2 -ZrO 2 -CuO and CeO 2 -ZrO 2 -MnO x which benefit from a synergetic interaction between CeO 2 (whose properties are already modified by the presence of Zr) and CuO or MnO x . Analysis of metal ion concentration in the effluents after reaction indicates also a high stability of the mixed-oxide catalysts under the conditions employed.
