<P>PROBLEM TO BE SOLVED: To provide an exhaust gas cleaning material having high catalytic activity in the combustion of PM (particulate matter) and capable of highly dispersing catalyst particles in order to sufficiently draw out high catalytic activity, and a method for preparing a catalyst slurry therefor. <P>SOLUTION: The exhaust gas cleaning material comprises at least two or more kinds of catalyst particles, an alkali metal salt and a heat-resistant structure having a three-dimensional structure, and the two or more kinds of the catalyst particles and the alkali metal salt are supported on the surface of the heat-resistant structure having the three-dimensional structure. Further, the catalyst slurry for the exhaust gas cleaning material is prepared by mixing at least two or more kinds of the catalyst particles, the alkali metal salt, water and two or more kinds of dispersants. <P>COPYRIGHT: (C)2003,JPO |
