Electrodes Based on Amorphous Metallic Aluminum Alloys in the Reactions of Hydrogen Release.

We estimate the electrochemical activity of specimens of the amorphous metallic alloys (АМA) AlNiY, AlNiYGd, and AlNiDyY in alkaline solutions of potassium hydroxide of different concentrations and the influence of partial substitution of 1 at. % Gd or Dy for Y. It is shown that all investigated specimens are corrosion-resistant in the course of cyclic polarization within the potential range from - 1.2 to + 1.0 V in aqueous KОН solutions of various concentrations (0.5-5.0) М. It is shown that AMA electrodes alloyed with 1 at.% Dy exhibit the highest catalytic activity in a 4 М KОН solution. [ABSTRACT FROM AUTHOR]
