FIELD: electricity.
SUBSTANCE: powdered composite Fe-C is applied to the electrode surface and synthesis is carried out for nanocrystal elements Fe-C with an average size within the range of 10-15 nm by treatment with laser pulses with wave length of 1-1.5 mcm at radiant density of 107-109 W/cm2, laser scanning rate of 8-15 cm/s, frequency of pulses of 33-60 kHz in vacuum or in argon, at that in the process melting and formation of ferric carbide Fe3C is not reached. The invention is also related to the iron-based cathode material for electrochemical production of hydrogen.
EFFECT: modification of iron surface that allows improvement of electrocatalytic activity for such material.
