EXHAUST GAS CATALYST, METHOD FOR THE PRODUCTION OF CARRIER, METHOD FOR THE PRODUCTION OF EXHAUST GAS CATALYST, AND APPARATUS FOR TREATING EXHAUST GAS

摘要

An exhaust gas controlling catalyst includes zirconia particles; ceria particles which contact the zirconia particles, of which a mean particle size is smaller than a mean particle size of the zirconia particles; and an active metal that is supported on at least the ceria particles in a dispersed manner.
