Designed synthesis and characterization of nanostructured ceria-zirconia based material with enhanced thermal stability and its application in three-way catalysis

The nanostructured CeO2-ZrO2-Y2O3-La2O3 materials with enhanced thermal stability and low-temperature reducibility were synthesized by co-precipitation with different hydrothermal temperature (100, 150, 180 °C). With improving hydrothermal temperature, the incorporation of rear earth metals was facilitated, and the surface properties were positively modified, which subsequently promotes Pd dispersion and stabilizes Pd at a more oxidized state.
