FIELD: chemistry.
SUBSTANCE: disclosed catalyst contains a single crystalline phase of a noble metal sulphide deposited on conducting carbon which essentially does not contain a phase of zerovalent metal or metal oxides, obtained via reduction of metal precursor salts and thio-precursors with boron hydride or another strong reducing agent.
EFFECT: high activity and stability of the catalyst for cathodic reduction of oxygen during electrolysis of hydrochloric acid.
