Abstract:
1. A manufacturing method of a catalytic converter, the method comprising: dispersing, in a solvent, a catalyst component and a disappearing material disappearing by heat, thereby obtaining a slurry; coating the obtained slurry on a three-dimensional structural support having a plurality of cells partitioned by porous cell walls, in which a pore diameter of the cell walls is 10 μm to 50 μm and porosity of the cell walls is 40 vol % or more; and baking the slurry-coated three-dimensional structural support to eliminate the disappearing material such that a catalyst-coated layer containing the catalyst component is formed on the surfaces of the cell walls of the three-dimensional structural support, and 50 mass % or more of a total supported amount of the catalyst component in the three-dimensional structural support is present on the surfaces of the cell walls.
