Abstract
A honeycomb-shaped substrate for catalyst is made from ceramic, has a straight-flow structure, and includes cellular walls exhibiting pore volumes, which differ partially, and a large number of cellular passages demarcated by the cellular walls. A catalyst for purifying exhaust gases is produced by providing the cellular walls of the honeycomb-shaped substrate with a catalytic coating layer.
