Ceramic catalyst body with better catalytic efficiency using a ceramic support which can directly attach the catalyst component, the ceramic catalyst body being obtained by direct attachment of a noble metal catalyst such as Pt a ceramic support obtained by substituting at least one of the constituent elements of cordierite which constitutes the ceramic substrate, for example Al, through W, a compound not containing chlorine, for example platinum dinitrodiammine, being used as the starting material of the noble metal catalyst. |
