CATALYST BODY AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a more highly activated catalyst material using the difference of catalytic activity by plane directions in the catalyst material comprising a catalyst composed of a metal or a metal oxide formed on the surface of a compound particle. SOLUTION: The catalyst body comprises a compound particle 1 composed of ceria and the like having a quasi-stable plane 1a, which is a plane having a quasi-stable plane direction, a catalyst 2 composed of the metal or the metal oxide such as Pt and Rh by succeeding an atomic arrangement of the quasi-stable plane direction on the quasi-stable plane 1a in this compound particle 1.
