FIELD: chemistry.SUBSTANCE: disclosed catalyst for low-temperature oxidation of carbon monoxide, which is silver deposited on a silicon dioxide surface in amount of 1-16% of the weight of the catalyst. The catalyst contains silver in the form of nanoparticles with a size smaller than 6 nm, which are uniformly distributed on the surface of mesoporous silica gel with specific surface area of 50-200 m/g and pore size of 3-60 nm, which is used as a support. The invention also relates to a method of using the catalyst to remove carbon monoxide from air, which is carried out using the catalyst by passing a stream of moist air containing up to 100-115 mg/mCO through the catalyst bed at room temperature.EFFECT: improved catalyst properties.4 cl, 1 tbl, 4 dwg, 5 ex |
