  • Patent number: 9315912
    Abstract: An improved carbon supported-noble metal sulphide electrocatalyst suitable for being incorporated in gas-diffusion electrode structures, in particular in oxygen-reducing gas-diffusion cathodes for aqueous hydrochloric acid electrolysis. The noble metal sulphide particles are monodispersed on the active carbon particles and the surface area ratio of noble metal sulphide particles to active carbon particles is at least 0.20.

  • Patent number: 8258072
    Abstract: The invention relates to a sulphide catalyst for electrochemical reduction of oxygen particularly stable in chemically aggressive environments such as chlorinated hydrochloric acid. The catalyst of the invention comprises a noble metal sulphide single crystalline phase supported on a conductive carbon essentially free of zerovalent metal and of metal oxide phases, obtainable by reduction of metal precursor salts and thio-precursors with a borohydride or other strong reducing agent.
