METHOD OF MAKING METAL-CONTAINING CARBON NANOSTRUCTURES Russian patent published in 2010 - IPC C01B31/02 B82B3/00 

FIELD: chemistry.

SUBSTANCE: invention can be used in coordination and colloidal chemistry. A mixture of organic substance and metallurgical dust containing 3d metals - iron or nickel undergoes mechanochemical processing and subsequently heated to (100-400)°C without access to air. The organic substance used is polymer production wastes which contain carbon-chain polymers with side functional groups such as secondary polyvinylchloride or polyvinylacetate. If polyvinylchloride is used, hydrochloric acid is added to the initial mixture. To obtain nano-products in form of "rolls" with metal oxide nanocrystals inside, the mixture is subjected to stage heating at temperature not exceeding 300°C, with subsequent alkali treatment of the product obtained in form of nanofilms with metal-containing nanoparticles on the surface.

EFFECT: invention enables to lower cost of the nano-product owing to use of production wastes and to also obtain nano-structures with magnetic susceptibility.
