PURPOSE:To lower the combustion temperature of particulates by combining Cu or Cu compounds, V or V compounds, and Zr, Al, Ni, Fe, Mn, La and Cr or their compounds to make a combination and by supporting the combination on the carrier. CONSTITUTION:At least one kind selected from Cu or Cu compounds, at least one kinds selected from V or V compounds, at least one kinds selected from Ar, Al, Ni, Fe, Mn, La and Cr or their compounds are combined and supported on the carrier to form the catalyst for purifying exhaust gas. Further, besides the above-mentioned compounds, Pt, Rh and Pd or their compounds can be added to form the catalyst for purifying exhaust gas. In order to support the catalyst on the carrier, the surface of the carrier is coated with alumina, etc., and the catalyst is supported on it through the coated surface. |
