nano-structures; сopper-carbon nanocomposites; synthetic humic substances


A new method for the synthesis of a copper-carbon nanocomposite using synthetic humic substances as a carbon source is presented. The method is based on the pyrolysis of copper (II) humate in reducing (Н2) and in inert atmosphere (Ar). The structure and properties of the Cu/C nanocomposites were characterized by X-ray diffraction (XRD), FT-IR spectroscopy, transmission electron microscopy (TEM), elemental analysis. The porous structure of Cu/C nanocomposite investigated using the nitrogen volumetric adsorption. Under the conditions of synthesis, a carbon matrix with a very low degree of ordering is formed. It was found that the dimensional and structural characteristics of copper nanoparticles depend on the synthesis conditions and vary from 40 to 80 nm. Carrying out the synthesis in a reducing atmosphere makes it possible to obtain copper-carbon nanocomposites that do not contain copper(I) oxide or copper(II) oxide phases. It was found that an increase in the pyrolysis temperature contributes to the improvement of the structure of the crystal lattice of the metal phase, an increase in the degree of carbonization of the organic component, and a change in the textural characteristics from mesoporous to microporous.
