Properties of cerium–zirconium mixed oxides partially substituted by neodymium: Comparison with Zr–Ce–Pr–O ternary oxides

CeO 2 doped with praseodymium, neodymium and/or zirconium atoms were prepared by coprecipitation and by the sol–gel method. Structural properties were investigated by in situ XRD and Raman spectroscopy while oxygen storage capacity (OSC) was measured by transient CO oxidation. All the compounds, exc...
