HOLLOW CARBON NANOPARTICLES, CARBON NANOMATERIAL AND METHOD FOR ITS PRODUCTION Russian patent published in 2015 - IPC D01F9/12 B82B1/00 B82B3/00 B01J13/02 C01B31/02 

FIELD: nanotechnology.

SUBSTANCE: group of inventions relates to the field of nanotechnologies, in particular to the technologies of production of carbon nanostructures and nanomaterials for use as substrates for applied catalysts, high-strength fillers, and relates to hollow carbon nanoparticles, carbon nanomaterial and method of its preparation. The carbon nanoparticle has an average size of not less than 5 nm, and comprises a central inner cavity and an outer closed casing enclosing the inner cavity on all sides. At that the outer casing comprises at least a pair of separate carbon layers. The carbon material comprises a mixture of hollow carbon nanoparticles comprising a central inner cavity and an outer closed casing enclosing the inner cavity on all sides. At that the outer casing comprises at least a pair of separate carbon layers, and the single-walled and double-walled carbon nanotubes. The method of producing the carbon material comprising a mixture of hollow carbon nanoparticles and single-walled and double-walled carbon nanotubes comprises catalytic decomposition of hydrocarbons at a temperature of 600-1200°C with obtaining a mixture of carbon nanoparticles, which is separated from the gaseous products and annealed at 1700-2400°C in the atmosphere of inert gas.

EFFECT: invention provides obtaining of novel carbon nanoparticles and nanomaterials having high strength at low weight, which can be used to create new composite light and high strength materials.
