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 m2/g or more in specific surface area and in the range of 100 ? to 700 ? in crystallite size.

Abstract: Provided is a particulate combustion catalyst including a carrier formed of monoclinic zirconium oxide particles, and metallic Ag or Ag oxide, which serves as a catalyst component and is supported on the carrier, wherein the amount of the catalyst component is 0.5 to 10 mass %, as reduced to metallic Ag, on the basis of the mass of the carrier, and preferably, the catalyst has a BET specific surface area of 8 to 21 m2/g. Also provided are a particulate filter coated with the particulate combustion catalyst; and an exhaust gas cleaning apparatus including a particulate filter coated with the particulate combustion catalyst.

Abstract: A catalyst for exhaust gas purification having superior exhaust gas purification performance is provided. Disclosed is a catalyst containing, as a catalyst support, a composite phosphate containing yttrium and phosphorus and having a composition ratio of yttrium to phosphorus (Y/P) of greater than 1 as a molar ratio.
