ABSTRACT:
A process for preparing a palladium catalyst for purifying a waste gas is disclosed. The process comprises dissolving dinitrodiammine palladium in a nitric acid solution in the temperature range of 60.degree. to 100.degree. C., aging the solution, applying the solution on a carrier, and reducing the palladium compound on the carrier to prepare the palladium catalyst.
The catalyst prepared has the excellent catalytic performance because the nitric acid solution of the dinitrodiammine palladium is a completely uniform solution which can disperse the dinitrodiammine palladium uniformly on the carrier.
