摘要: The oxidation catalyst for exhaust gas purification provided by the present invention includes a support supporting a noble metal that catalyzes the oxidation of carbon monoxide (CO). The support is mainly constituted by a composite metal oxide including, in terms of oxides, Al and Zr, or Al, Zr and Ti at the following mass ratios: Al2O3 40 to 99% by mass, ZrO2 1 to 45% by mass, and TiO2 0 to 15% by mass.

摘要: The exhaust gas purification catalyst according to the present invention has a substrate 54, a lower layer 57 disposed on this substrate 54, and an upper layer 58 disposed on this lower layer 57. The upper layer 58 is provided with a first catalyst and a second catalyst, and the lower layer 57 is provided with a first catalyst. This first catalyst has Al2O3 as a carrier and Pt and Pd as noble metals supported on the Al2O3, while the second catalyst typically has an Al2O3—ZrO2—TiO2 complex oxide as a carrier and has Pd as a noble metal supported on the Al2O3—ZrO2—TiO2 complex oxide. Moreover, the upper layer 58 has a hydrocarbon adsorbent 68.
