Abstract
The exhaust gas purification catalyst according to the present invention has a substrate, a lower layerdisposed on this substrate, and an upper layerdisposed on this lower layer. The upper layeris provided with a first catalyst and a second catalyst, and the lower layeris provided with a first catalyst. This first catalyst has AlOas a carrier and Pt and Pd as noble metals supported on the AlO, while the second catalyst typically has an AlO—ZrO—TiOcomplex oxide as a carrier and has Pd as a noble metal supported on the AlO—ZrO—TiOcomplex oxide. Moreover, the upper layerhas a hydrocarbon adsorbent
