FIELD: chemistry.
SUBSTANCE: catalyst contains nanoparticles of precious metal compounds, such as platinum, palladium, and iridium, with the molar ratio of elements (Pt+Pd):Ir equal to 1:x, where x ranges from 0.02 to 0.67 on porous media with a specific surface area of the pores from 50 to 500 m2/g. A method of producing a catalyst and a method of making compound-predecessor of iridium are also provided.
EFFECT: invention makes it possible to produce a catalyst characterized by a high stability of the catalytic properties with long service lives.
