It was highly evaluated that the technology of pyrochlore type CeO2-ZrO2 material would contribute to the development of the automobile field, and it was the first time for us, Cataler, to receive a Technical Paper Award.


The authors focused on the pyrochlore structure CeO2-ZrO2, which is characterized by “slower and higher capacity” oxygen storage characteristics than before and worked on the development of this material and the practical application of catalysts using it.
In particular, the following three issues, “high temperature heat resistance (derived from the crystal structure of the metastable phase)”, “performance in the low temperature range”, and “improvement of responsiveness to gas atmosphere” have been improved over three generations. This has contributed to the expansion of applicable models and the global expansion of vehicles with low environmental impact.

It is also highly evaluated that it contributed to reducing the amount of precious metals used as a benefit of higher performance.
