Abstract

Provided is an exhaust-gas-purification catalyst carrier that contains a ceria-zirconia complex oxide having a pyrochlore phase and a novel exhaust-gas-purification catalyst carrier that exhibit excellent OSC performance at any temperature region of a low temperature (around 400° C.) and a high temperature (around 800° C.). Proposed is the exhaust-gas-purification catalyst carrier containing a ceria-zirconia complex oxide which has a pyrochlore phase and is 7.0 m/g or more in specific surface area and in the range of 100 Å to 700 Å in crystallite size.
