Catalyst body and method of producing the same |
摘要 |
The present invention can realize a catalyst body which can efficiently achieve a catalytic reaction with a minimum required amount of catalyst and can exhibit high catalytic performance at low cost. According to the present invention, a catalyst component can be directly supported on the surface of a substrate ceramic and the catalyst component is directly supported on a ceramic carrier 11 having a honeycomb structure which has plural cells 2 partitioned with a cell wall 3. 90% or more of the catalyst component is supported at an outermost layer 4 of the cell wall 3, for example, the portion ranging from the surface to a depth of 30 mum or less, thereby to reduce the amount of the catalyst component which does not contribute to the purification reaction and to reduce the catalyst cost.
