FIELD: chemistry.

SUBSTANCE: invention relates to field of production of catalysts, containing porous carrier (active aluminium oxide) and deposited on it catalytically active metal (palladium) for low-temperature oxidation of carbon oxide and can be used in means of individual and collective protection of respiratory organs of people. Described is method of obtaining palladium catalyst on active aluminium oxide for low-temperature oxidation of carbon oxide, including preliminary modification of aluminium oxide with nickel oxide in amount (0.03-0.50) % wt, impregnation with acidified with hydrochloric acid solution of palladium (II) chloride, in amount (0.1-1.5) % wt in terms of metal, reduction with sodium formiate solution with rate of solution feeding (0.1-0.4) cm/s with further washing and drying of catalyst first at room temperature during (1-2) h, then at temperature (30-40)°C during (1-2) h and then to temperature (105-115)°C with rate of its increase (10-15)°C/h.

EFFECT: obtaining more efficient catalyst for carbon oxide oxidation in wide range of its concentrations at room temperature of use.
