METHOD FOR SYNTHESIS OF METAL-CARBON NANOCOMPOSITE FeCo/C Russian patent published in 2015 - IPC C01B31/02 B82B3/00 B82Y30/00 

FIELD: chemistry.

SUBSTANCE: invention relates to chemistry and nanotechnology. The method includes first preparing a solution of polyacrylonitrile (PAN) and acetyl acetonate Fe(CH₃COCH=C(CH₃)O)₃·6H₂O in dimethyl formamide at 40°C; adding cobalt acetate solution Co(CH₃COO)₂·4H₂O to the dimethyl formamide; concentration of PAN is 5% of the weight of dimethyl formamide and concentration of iron and cobalt is 5-20% and 5-20% of the weight of PAN, respectively; holding the solution until complete dissolution of all components, followed by removal of dimethyl formamide by evaporation at temperature not higher than 70°C. The obtained solid residue is heated with high-intensity infrared radiation by holding for 15 minutes at 150°C-200°C and then for 10 minutes at final temperature of 600-800°C. Heating the solid residue at all steps is carried out at a rate of 20°C/min at pressure in the reaction chamber of 10^-2-10^-3 mmHg. The obtained metal-carbon nanocomposite FeCo/C contains FeCo nanoparticles with size of 5-50 nm.

EFFECT: avoiding the need to use additional reducing agents.
