NANOCOMPOSITE BASED ON NITROGEN-CONTAINING CARBON NANOTUBES WITH ENCAPSULATED COBALT AND NICKEL PARTICLES AND METHOD OF OBTAINING THEREOF Russian patent published in 2015 - IPC C01B31/02 B82B3/00 B82Y30/00 

FIELD: chemistry.

SUBSTANCE: invention relates to the field of chemical technology of obtaining composite carbon-metal materials and can be used in the production of catalysts, sorbents, polymer fillers, pharmaceutical preparations, immobile chromatographic phases. The nanocomposite material consists of atoms of carbon, nitrogen and nickel and cobalt nanoparticles encapsulated into the structure, which is formed by the said atoms. The carbon atoms form conic multi-wall carbon nanotubes, with the nitrogen atoms being localised on plane ends or in places of structural defects. The metal nanoparticles are located on ends of the nanotubes, in subsurface layers, with the formation of structural defects, as well as inside a channel. The method of the material preparation consists in the injection of a solution of chlorides, acetates or acetylacetonates of cobalt or nickel in toluene or benzene in a mixture with ethanol with the addition of trimethylamine or tetramethylethylenediamine into a nitrogen-blown high-temperature hermetic reactor at a temperature of 580-600°C.

EFFECT: invention makes it possible to simplify the process, reduce energy consumption and increase the production safety.
