Abstract: A film of a noble metal is deposited on the surface of a carrier without substantial penetration of the carrier by immersing the carrier first in a dilute solution of a salt of the noble metal, removing the carrier and heating and drying it to produce precipitation cores of the noble metal on the surface of the carrier, and then immersing the carrier with the precipitation cores in a solution of a noble metal salt which also contains a reducing agent for the salt and a stabilizer for the solution. The film of noble metal thus produced on the surface is adherent thereto and is highly active as a catalyzer for removing pollutants from the exhaust gas of an automobile.
