CATALYST FOR CLEANING EXHAUST GAS

摘要

PROBLEM TO BE SOLVED: To provide a catalyst capable of exhibiting the performance more excellent than before when used for cleaning exhaust gas even if the catalyst contains a small amount of a noble metal.

SOLUTION: The catalyst for cleaning exhaust gas includes: a carrier base material which has a plurality of through-holes in the flowing direction of the exhaust gas; one or a plurality of catalyst-deposited layers formed on the inner wall surface of each of the through-holes; and the noble metal deposited on each of the catalyst-deposited layers. The thickness of each of the catalyst-deposited layers is adjusted so that the pressure of the exhaust gas passing through the through-holes becomes uniform among all the through-holes.
