<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a catalyst for treating an exhaust gas capable of well controlling the compound supported within a coating layer, and the catalyst for treating the exhaust gas. <P>SOLUTION: A first solid carrier component based on CeO<SB>2</SB>and a second solid carrier component comprising at least one component selected from the group consisting of TiO<SB>2</SB>, Al<SB>2</SB>O<SB>3</SB>, ZrO<SB>2</SB>, SiO<SB>2</SB>, La<SB>2</SB>O<SB>3</SB>and a composite oxide of them are immersed in a raw material liquid containing a noble metal and the impregnated carrier components are burned to obtain a catalyst support component and, after the catalyst support component is adjusted in its particle size, the catalyst support component is immersed in a raw material liquid containing an alkali metal and/or an alkaline earth metal to prepare a catalyst slurry which is, in turn, applied to a base material by wash coating. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
