Patent ID: 8038955

Claim:
A catalyst supporting honeycomb comprising: a pillar-shaped honeycomb structure having a plurality of cells formed in parallel with one another in a longitudinal direction with a cell wall interposed therebetween; and catalyst particles supported on the honeycomb structure, said honeycomb structure having an integral honeycomb structure comprising a single member obtained by extrusion-molding a mixture comprising inorganic fibers and an inorganic material, said inorganic material melting at a temperature of a heat-resistant temperature of the inorganic fibers or lower, a porosity of said cell wall being about 70% or more, said catalyst particles being configured by an oxide catalyst having an average particle diameter of at least about 0.05 μm and at most about 1.00 μm, wherein said inorganic fibers are fixed to each other through the inorganic material at intersection portions of the inorganic fibers, and wherein said inorganic material is present locally at said intersection portions of the inorganic fibers.
