FIELD: technological processes.
SUBSTANCE: invention relates to a method for producing electrode materials for fuel cells and supercapacitors, including electrochemical dispersion of an alkali metal hydroxide in solution, electrochemical oxidation with simultaneous deposition of the formed nanoparticles of platinum or nickel oxide on a carbon carrier under the influence of alternating current, washing and drying of the finished material. Method is characterized by the fact that the process of electrochemical synthesis is carried out for 2.5 hours using platinum or nickel electrodes with an area of up to 20 cm2, placed at a distance of 3 cm when exposed to alternating current with pulses of various shapes and an average density of 1÷2 A/cm2.
EFFECT: proposed method allows to obtain high-speed Pt/C and NiO/C electrochemical production of electrode materials with platinum particle sizes of 5÷18 nm and particle size of nickel oxide 100÷400 nm under conditions of increasing production scale.
