Abstract

The composite La–Ni–Al/Ni–S alloy film was obtained by molten salt electrolysis and aquatic electrodeposition in turn. The La–Ni–Al alloy film was prepared in Na3AlF6–La2O3–Al2O3 molten salt electrolyte by galvanostatic electrolysis at 100 mA cm−2. The results showed that La3+ and Al3+ ions could be co-reduced on the nickel cathode and form La–Ni–Al film at c.a. −0.5 V, which is much lower than that of the theoretical decomposition potential of lanthanum and aluminum. With high HER activity, the composite La–Ni–Al/Ni–S film (η150 = 70 mV, 353 K) could absorb large amount of H atoms. Instead of the dissolution of the Ni–S film, the absorbed H atoms would be oxidized under intermittent electrolysis effectively and prolong the lifetime of the cathode.
