Electrochemical hydrogen evolution on oxidized electrodes of the amorphous metallic alloys Fe₈₂Nb₂B₁₄RE₂ (RE = Tb, Dy) in 5.0 M KOH aqueous solution in the temperature range 298-313 ± 0.5 K has been investigated. A sample Fe₈₄Nb₂B₁₄ was used as reference alloy. The highest corrosion resistance during multiple scanning of the potential exhibited the alloys doped by terbium and dysprosium. High values of the exchange currents, characterizing catalytic ability and corrosion resistance characterize Fe₈₂Nb₂B₁₄RE₂ amorphous alloys as promising electrode materials for hydrogen evolution reaction.
