FIELD: chemistry.
SUBSTANCE: claimed invention relates to catalysts from metals of platinum group on oxide carrier, intended for removal of harmful components, in particular of gaseous carbon monoxide in engine exhaust fumes of automobile engines or for application in electrodes of gas-sensitive sensors, in fuel elements, which work on synthesis-gas, and in other electrochemical devices. Described is nano-structured catalyst for after-burning of carbon monoxide, which as carrier contains tin dioxide, alloyed with antimony oxide with ratio of antimony to tin being 2 mol % and particles of nano-crystalline platinum, content of which in catalyst constitutes 2 wt %, with oxide carrier having one-phase composition, and particles of nano-crystalline platinum, precipitated on oxide carrier, have size 3-5 nm.
EFFECT: obtaining highly active catalyst for carbon monoxide oxidation.
