Exhaust gas purifying catalyst and production method thereof |
摘要 |
An object is to maintain an effect of enhancing activity of noble metal particles by transition metal without increasing production cost and an environmental load. An exhaust gas purifying catalyst 1 is composed of: noble metal particles 2; first compounds 3 which contact the noble metal particles 2 and suppress movement of the noble metal particles 2; and second compounds 4 which contain the noble metal particles 2 and the first compounds 3, suppress the movement of the noble metal particles 2, and suppress coagulation of the first compounds 3 following mutual contact of the first compounds 3, wherein the first compounds 3 support the noble metal particles 2, and simplexes or aggregates of the first compounds 3 supporting the noble metal particles 2 are included in section partitioned by the second compounds 4.
