Abstract
According to a first embodiment of a production method of an oxidation catalyst device for exhaust gas purification of the present invention, a plurality of slurries containing a catalyst precursor prepared from mutually different organic acids is coated respectively on a porous filter carrier () and calcined. According to a second embodiment of the present invention, the slurry contains the catalyst precursor having a particle diameter distribution ranging from 0.5 to 10 μm, and the slurry has a viscosity equal to or below 2.0 mPa·s. The oxidation catalyst device of the present invention is composed of a composite metal oxide on a surface of a cell division and a surface of an air pore of the porous filter carrier having a wall-flow structure.
