METHOD OF PRODUCING GRAPHITE ELECTRODES WITH COATING, PREFERABLY OF NOBLE METALS, FOR ELECTROLYTIC PROCESSES, ESPECIALLY FOR HYDROCHLORIC ACID ELECTROLYTES Russian patent published in 2014 - IPC C25B11/14 

FIELD: chemistry.

SUBSTANCE: described is a method of producing graphite electrodes with a coating, preferably of noble metals, for electrolytic processes, particularly for hydrochloric acid electrolytes, wherein the surface of a graphite electrode is coated with an aqueous solution of a noble metal compound, followed by heat treatment of the graphite electrode in the presence of reducing gases and/or gases which do not primarily contain oxygen at temperature of 200-450°C.

EFFECT: longer service life of graphite electrodes used when producing chlorine and hydrogen.
