Abstract:
The present invention provides a cerium oxide-zirconium oxide-based mixed oxide having superior platinum dispersibility and a suitable OSC, and a simple production process thereof. The cerium oxide-zirconium oxide-based mixed oxide comprises cerium oxide and zirconium oxide, wherein (1) the weight ratio of CeO2:ZrO2 is 60:40 to 90:10, and (2) the cerium oxide and the zirconium oxide are present as a mixture, the zirconium oxide being composed of a solid solution in which tetragonal or cubic zirconium oxide contains cerium.
