ABSTRACT:
A catalyst for purifying exhaust gas may be prepared by a process comprising impregnating a ceramic carrier with an impregnating liquid containing at least one Platinum Group metal compound, at least one organic nitrogen compound and/or at least one organic phosphorus compound, drying the impregnated carrier, reducing the metal compound impregnated in the carrier to the corresponding metal and then calcining the metal on the carrier to obtain the desired catalyst. This invention also relates to the catalysts prepared by said process.
