FIELD: chemistry.
SUBSTANCE: particles of a noble metal sulphide are mono-dispersed on activated carbon particles whose surface area is between 200 and 300 m2/g. The ratio of the surface area of the particles of noble metal sulphide to the surface area of particles of activated carbon is less than 0.20.
EFFECT: high catalyst activity during electrochemical reduction of oxygen, high stability thereof in chemically aggressive media.
