A honeycomb structured body of the present invention comprises a plurality of cells placed in parallel with one another in a longitudinal direction with a cell wall therebetween, wherein an oxide catalyst is supported on at least one portion of the cell wall, and the honeycomb structured body has an apparent density of about 0.7 g/cmor less.

Honeycomb structured body and exhaust gas purifying device

A catalyst supporting honeycomb including 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. The catalyst particles include an oxide catalyst, an average particle diameter of which is at least about 0.05 &#x3bc;m and at most about 1.00 &#x3bc;m.

Catalyst supporting honeycomb and method of manufacturing the same

A catalyst supporting honeycomb includes a pillar-shaped honeycomb structure and catalyst particles supported on the honeycomb structure. The honeycomb structure includes cell walls extending in a longitudinal direction of the honeycomb structure to define a plurality of cells extending in the longitudinal direction. The plurality of cells include large-volume cells having first opening ends and second closing ends opposite to the first opening ends along the longitudinal direction, and small-volume cells having first closed ends and second opening ends opposite to the first closed ends along the longitudinal direction. Total cross sectional areas of the large-volume cells on a plane perpendicular to the longitudinal direction are larger than total cross sectional areas of the small-volume cells on the plane. The catalyst particles include an oxide catalyst having an average particle diameter of at least about 0.05 &#x3bc;m and at most about 1.00 &#x3bc;m.

A pillar-shaped honeycomb structure has a plurality of cells longitudinally placed in parallel with one another with a wall portion therebetween, wherein the honeycomb structure mainly includes inorganic fibers which form the honeycomb structure without lamination interfaces.

Honeycomb structure and method for manufacturing honeycomb structure

A honeycomb filter includes a honeycomb structure in which a plurality of cells are placed in parallel with one another in the longitudinal direction with a cell wall therebetween; and a cylindrical metal casing that covers the outer peripheral side face of the honeycomb structure. A shortest distance between the outermost cells among the plurality of cells and the inner face of the metal casing is at least about 1 mm and at most about 3 mm.
