Anewsynthesis route driving redox-precipitation reactions among MnVII,CeIII andMnII precursors in basic aqueous solution yields MnCeOx catalysts (Mn loading, 9–33 wt%) with improved textural and structural properties in comparison to the conventional coprecipitation technique. Irrespective of the Mn loading, BET, X-ray diffraction (XRD), transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS) findings prove that the newmethod ensures a very high reproducibility in all themain physicochemical properties of MnCeOx catalysts. Enabling a monolayer dispersion of the active phase, the ‘‘redox-precipitation’’ method greatly promotes the reducibility and the surface affinity of the MnCeOx system towards gas-phase oxygen.
