Abstract
A storage catalystis constituted of a supporter substrate, which is formed of at least one member being selected from the group consisting of AlO, CeO, ZrO, TiOand zeolite, and whose specific surface area is 30 m/g or more, and a coating layer, which includes a supporting powder including at least one member being selected from the group consisting of AlO, CeO, ZrO, TiOand zeolite, a storage material for storing NOand SO, the storage material being supported on the supporting powder, and a noble metal being supported on the supporting powder. Since the supporter substratehas a large specific surface area, a supporting amount of the storage material for storing NOand SOaugments remarkably. Therefore, an SOstorage amount of the storage catalyst, which is put in place on an upstream side of an NOstorage-and-reduction catalyst, augments, and thereby an NOstorage amount in low-temperature regions augments.
