FIELD: chemistry.

SUBSTANCE: invention relates to catalysts for low-temperature oxidation of carbon monoxide (CO), a method of producing said catalysts and a method of oxidising CO in order to protect the environment from CO pollution. The catalyst for oxidising carbon monoxide is a Pd/C-K composition, where: C is a mesoporous carbon material obtained via carbonisation of rice husks, K is kaolin which contains aluminium, silicon, titanium, iron and calcium oxides. The catalyst is made by saturating a nanocomposite carbon-containing support with an alcohol solution containing palladium nitrate with palladium content 2-5%,said support having the following texture characteristics: S_BET=450-470 m²/g, V_por=0.5-0.6 cm³/g, d_por=3.3-3.5 nm. The carbon-containing support is made through carbonisation of rice husks in a reactor with a copper-chromium catalyst fluidised-bed at temperature 450-470°C, through activation thereof with KCO₃ at temperature 850-900°C and then mixing with kaolin in weight ratio 2/3-1/1 and with water and then moulding. Carbon monoxide is oxidised in the presence or absence of water in a reaction mixture and the catalyst described above.

EFFECT: complete oxidation of carbon monoxide CO at room temperature and suitable moisture content.
