CATALYST BODY

摘要

PROBLEM TO BE SOLVED: To obtain a catalyst body causing little deterioration of the catalyst due to heat and keeping higher catalytic performance for a long time.

SOLUTION: The catalyst body is obtained by directly chemically adsorbing the catalyst component such as Pt to Zr, W or the like substituted for the element on a carrier such as Al in cordierite without forming a coating layer. By selecting the combination of the catalyst component and the element in the carrier so as to obtain >5 eV carrier intensity by the simulation using the density functional formalism, coarsening of the catalyst particles can be suppressed and a high-performance catalyst body having excellent thermal durability can be obtained.
