| 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. |
