METHOD OF PRE-TREATMENT OF CARBON-BEARING CARRIER OF ELECTROCHEMICAL CATALYSER Russian patent published in 2013 - IPC C25B9/00 C25B9/04 C25B9/10 B01J21/18 B01J37/30 B01J37/34 B82B3/00 

FIELD: metallurgy.

SUBSTANCE: treatment of carbon-bearing carrier of an electrochemical catalyser is performed in a vacuum chamber equipped with a source of flow of atomic particles and a holder of carbon powder, which has the possibility of mixing the powder; powder of carbon-bearing carrier is mixed, and surface of the carrier is bombarded with a beam of atomic particles; besides, in order to arrange powder of carbon-bearing carrier, there used is a porous substrate installed in the holder and having open porosity, and made from inert material, and pneumatically connected to an autonomous gas supply device; layers of particles of carbon-bearing carrier are put on the substrate; inert gas is blown through the porous substrate so that a fluidised layer of carbon-bearing carrier particles is formed above the substrate, and bombardment of surface of particles of carbon-bearing carrier is performed with ion energy of not less than 7.41 eV/atom.

EFFECT: improving activation efficiency of surface of fine and nanosized carrier of electrochemical catalysers.
