HONEYCOMB STRUCTURE, HONEYCOMB STRUCTURE TYPE CATALYST, AND PRODUCTION METHODS THEREFOR
Provided are a honeycomb structure capable of preventing catalyst slurry from leaching out to an outer portion thereof when applying a wash coat for making a catalyst supported, a honeycomb structure type catalyst which is capable of ensuring air permeability of the outer portion and in which there is no occurrence of cracking when used as a gasoline particulate filter (GPF), and production methods therefor.A honeycomb structure for producing a catalyst, the honeycomb structure having: a honeycomb substrate composed of porous partition walls forming a plurality of cells and a porous outer portion; and a resin composition on the outer portion of the honeycomb substrate, wherein the outer portion and the partition walls of the honeycomb substrate are formed of the same material; a porosity of the honeycomb structure is 50% or more; and the resin composition is impregnated into pores of the whole outer portion; and the impregnation depth is equal to the outer portion thickness or a part of the resin composition is impregnated deeper than the outer portion and reaches the cell partition walls.
