METHOD FOR SYNTHESIS OF COMPOSITE CARBON MATERIAL WITH METAL NANOPARTICLES WITH TRANSFER OF PART OF THEIR ELECTRONIC DENSITY INTO CARBON MATRIX Russian patent published in 2019 - IPC C01B32/05 B82Y40/00 C04B35/52 B82B3/00 B82Y30/00 

FIELD: technological processes.

SUBSTANCE: invention can be used in chemical and metallurgical industry, as well as in power engineering. First, a metal salt from the solution is applied on the surface and volume of pores of the carbon material used as a matrix. Metal ions are then reduced while continuously monitoring the state of metal ions and the carbon matrix from in-situ spectroscopy of electronic paramagnetic resonance, or dielectric spectroscopy, or matrix conductivity. Reduction is completed at a sudden change in the conductivity of the carbon matrix, sorption energy, rate of diffusion of gas molecules in the pores of the material, factor of spectroscopic splitting (g-factor) of the EPR spectrum, relaxation time of resonance transitions of unpaired electrons. Composite carbon material with metal nanoparticles is obtained.

EFFECT: sharp increase in conductivity, heat conductivity, appearance of ferromagnetic properties.
