Abstract

PURPOSE: When catalytic carrier is provided with a specific amount of one or more of platinum group metals, such amount is devided into two or more sections for being carried, thus effecting the production of catalyst having good performance and endurance.
CONSTITUTION: A solution containing one or more of platinum group metals is used as impregnation material to be carried by carrier. A first carrying process may be immediately followed by next carrying process, or after washing, drying, or chemical treating processes, next process may be done. Impregnating material is not necessary to be the same composition. For example, pH of the solution or catalytic metal component may be changed. Further, the component may include additive agent, other platinum goup metal as well as auxiliary ingredient. After final carrying process, washing, drying, and firing processes are performed.
