Provided is a carrier for an exhaust gas purification catalyst containing aluminum borate particles having a peak (pore peak) exhibiting the highest intensity in a void volume diameter range of from 20 nm to 100 nm in a logarithmic differential void volume distribution measured using a mercury intrusion porosimeter, in order to provide a new catalyst support capable of effectively suppressing a decrease in catalytic performance caused by sulfur (S) component contained in the exhaust gas, in the case of supporting Pd as a catalytically active component.

Carrier for exhaust gas purification catalyst, and exhaust gas purification catalyst

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 m/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.
