<P>PROBLEM TO BE SOLVED: To provide a manufacturing method for an exhaust gas cleaning catalyst capable of simplifying a manufacturing process, capable of reducing the thickness of a catalyst substrate and the weight of a catalyst and capable of sharply reducing a production cost. <P>SOLUTION: The manufacturing method (1) for the exhaust gas cleaning catalyst includes a process for preparing a catalyst carrier by coating a catalyst substrate made of a metal with a slurry obtained by mixing titanium oxide, water and colloidal silica and/or an inorganic fiber to prepare a catalyst carrier and a process for infiltrating an aqueous solution of a compound containing vanadium and molybdenum or a mixed solution prepared by mixing colloidal silica with the aqueous solution into the catalyst carrier to support the compound. The catalyst substrate made of the metal (2) is a catalyst substrate structure obtained by integrally laminating the catalyst substrate, which has linear wavy, uneven or tiered projections formed thereto, to the surface of a tabular substrate. <P>COPYRIGHT: (C)2004,JPO |
