A catalytic converter includes: 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 a catalyst-coated layer containing a catalyst component. The catalyst-coated layer is coated on surfaces of the cell walls of the three-dimensional structural support. 50 mass% or more of a total supported amount of the catalyst component on the three-dimensional structural support is present in a region from the surfaces of the cell walls of the three-dimensional structural support to surfaces of the catalyst-coated layer.
The manufactured catalytic converter may be used as a diesel particulate filter of the coated honeycomb type. The converter provides the advantages of improved soot oxidation and a decrease of pressure loss due to the mere surface coating without pore filling. |
