FIELD: carbon monoxide oxidation catalysts applicable in cleaning gases from carbon monoxide. SUBSTANCE: new catalyst includes manganese dioxide and lead dioxide, and is distinguished by the fact that it presents anode slime formed on lead anode in electrolytic reduction of zinc from acid sulfate solutions preliminarily washed from electrolyte and dried, and containing, wt. %: manganese dioxide above 50; lead dioxide up to 15; silver oxide up to 0.15; the balance, additives. EFFECT: higher separation efficiency of exhaust gases from ecologically hazardous components, high process economic efficiency. 6 tbl
