The possibility of making electrode nanocomposite materials for supercapacitors by adsorption of transition metal salts from aqueous solutions by the porous carbon matrix with subsequent heat treatment has been investigated. It is shown for the carbon - Co3O4 system as an example that this method allows obtaining nanocomposites with the content of filler (elemental cobalt) up to 3 wt%. The introduction of the filler using this method only slightly reduces the specific surface area and pore volume of the composites with respect to the initial carbon matrix. The product obtained by thermal decomposition of cobalt(II) nitrate at 240 °C cannot be identified by X-ray diffraction, but according to the data of differential thermal analysis, it catalyses thermal oxidation of the porous carbon matrix in air. It is shown by cyclic voltammetry that the electrode materials obtained by the adsorption method have a higher specific capacitance compared to the original carbon matrix or composites obtained by inserting the filler as the solid phase.
