PROBLEM TO BE SOLVED: To obtain a ceramic catalyst using a ceramic carrier which can directly carry the catalyst component. SOLUTION: When the ceramic catalyst is produced by directly supporting a noble metal catalyst such as Pt on a ceramic carrier prepared by substituting W for one or more kinds of elements, for example Al, in the structural elements of cordierite as the base ceramic material, a compound containing no chlorine such as dinitrodiammine platinum or the like is used as the start source material of the noble metal catalyst. The method prevents residual chlorine from inhibiting the support for the catalyst, increases the carried amount of the catalyst and improves the catalytic performance. |
