FIELD: chemistry.
SUBSTANCE: invention relates to field of catalysis. Described is method of obtaining catalyst, which includes impregnation of metal oxide substrate material with platinum compound, drying below the point of said platinum compound decomposition, burning in gas flow, which contains NO and inert gas. Described is application of said catalyst as oxidation catalyst, and catalyst unit in the system of exhaust gas purification.
EFFECT: increased activity and selectivity of CO and NO oxidation.
