Catalyst supporting honeycomb

摘要

The present invention aims to provide a catalyst supporting honeycomb which can improve the continuous regeneration performance of soot and economically keep the amount of soot that accumulates with time on the cell walls small. The catalyst supporting honeycomb of the present invention includes a pillar-shaped honeycomb structured body 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 structured body, the plurality of cells comprising a set of large-volume cells in which either end of each of the cells is sealed, and a set of small-volume cells in which the other end of each of the cells is sealed, the total area of the set of large-volume cells in the cross section perpendicular to the longitudinal direction being larger than the total area of the set of small-volume cells in the cross section perpendicular to the longitudinal direction, and the catalyst particles being configured by an oxide catalyst having an average particle diameter of 0.05 µm to 1.00 µm.
