Abstract
A novel catalyst constituent material for combustion gas purification, which has an extremely good ratio of contact between each catalyst metal particle and an exhaust gas; and a catalyst device which uses this catalyst constituent material for combustion gas purification; and a method for producing this catalyst constituent material for combustion gas purification. The catalyst constituent obtained by mixing catalyst metal particles and a pore-forming material that disappears at high temperatures into a catalyst supporting material, which is a slurry containing fine ceramic particle. The pore-forming material also contains long fibers of cellulose nanofibers and/or short fibers of cellulose nanofibers.
