METHOD FOR MANUFACTURE OF POROUS METAL-CARBON MATERIALS Russian patent published in 2018 - IPC C01B32/05 H01M4/90 H01M4/04 H01G9/04 C08J9/36 B01J21/18 B01J23/70 

FIELD: manufacturing technology.

SUBSTANCE: invention can be used in the manufacture of fuel cell electrodes, two-layer capacitors, lithium-ion or lithium-polymer batteries, as well as catalysts or adsorbents. Layer of a polymer complex of a transition metal with a Schiff base of the form [M(Shiff)]n, having a repeating fragment of the following structure, is deposited on a conductive substrate, for example a glassy carbon plate, with a repeating fragment of the following structure: where n is an integer in the range from 2 to 50,000; M is a transition metal selected from the group consisting of nickel, palladium, platinum, cobalt, copper, iron; Shiff is a tetradentate ligand selected from the group consisting of Salen (residue of bis-(salicylaldehyde)-ethylene diamine), Saltmen (residue of bis-(salicylaldehyde)-tetramethylethylenediamine), Salphen (residue of bis-(salicylaldehyde)-o-phenylenediamine); R is a substituent at the Schiff base selected from the group consisting of H- and carbon-containing substituents, preferably CH3-, C2H5-, CH3O-, C2H5O-; and Y is the diamine bridge at the Schiff base, having the following structure: —CH2—CH2— for the base of Schiff Salen, for the base of Schiff Saltmen, for the base of Schiff Salphen. Then heating is carried out in an inert atmosphere to 500–750 °C for 1–4 hours before completion of the carbonization process of the polymer complex. Inert atmosphere is created by one or several gases selected from the group consisting of nitrogen, argon and helium. Before heating, the substrate coated with said complex can be washed using acetonitrile.

EFFECT: obtained electrochemically active metal-carbon material has high electronic conductivity, specific surface, controlled elemental composition and pore size distribution, while the metal atoms are evenly distributed inside it.
