Manufacturing method of catalyst layer forming material, manufacturing method of catalyst apparatus constituting material, and manufacturing method of catalyst device

摘要

[Problem] The technical issue was the development of a new catalyst constituent material for purifying combustion gas, a catalyst device using the catalyst, and a manufacturing method thereof, which have an extremely good contact rate between individual catalyst metal particles and exhaust gas. SOLUTION: A catalyst metal particle 3 and a porous forming material 5 which disappears at a high temperature are mixed with a catalyst supporting material 2 which is a slurry containing fine particles of ceramics, and the porous forming material 5 is made of cellulose nanofibers. It is characterized by containing 5 L of long fibers and / or 5S of short fibers of cellulose nanofibers. [Selection diagram] Fig. 1
