EXHAUST GAS PURIFICATION OXIDATION CATALYST

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: Al 2 O 3 40 to 99% by mass, ZrO 2 1 to 45% by mass, and TiO 2 0 to 15% by mass.
