摘要: The present invention provides a cerium oxide-zirconium oxide based composite that has large OSC at low temperature and suitable OSC, method for readily producing the oxide. Specifically, comprising mixture of (1) cerium-zirconium from melting process (2) dioxide wet process, oxide, dispersing in cerium-containing solution, neutralizing resulting dispersion; then performing heat treatment.
