METHOD OF MODIFYING ELECTROCHEMICAL CATALYSTS ON CARBON SUPPORT Russian patent published in 2013 - IPC C25B9/00 C25B9/04 C25B9/10 B01J21/18 B01J37/30 B01J37/34 B01J23/40 B82B3/00 

FIELD: chemistry.

SUBSTANCE: described is a method of modifying electrochemical catalysts on a carbon support, involving performing modification in a vacuum chamber equipped with a controlled source of a stream of atoms or ionised atoms of the modifying material, a device for feeding inert gas and a holder for the processed catalyst; the modified surface of the obtained catalyst on a carbon support is treated with a stream of atoms or ionised atoms of the modifying material, wherein the synthesised catalyst is placed on a fine carbon support using an open porosity porous substrate mounted on the holder, made from an inert material, pneumatically linked to the device for automatically feeding gas; inert gas is blown through the porous substrate to form pseudo-fluidised layer of particles of a carbon support with the modified catalyst over the substrate; the catalyst is then treated with a stream of atoms or ionised atoms of the modified material.

EFFECT: high efficiency of modifying electrochemical catalysts and operational characteristics thereof.
