Raney-Ni cathodes were prepared by leaching aluminum from Ni-Al precursor alloys (NiAl3, Ni2Al3, NiAl, and Ni3Al). The catalytic activity for the hydrogen evolution reaction was investigated in 1 M NaOH at 303 K. The hydrogen overpotentials of Raney Ni electrodes obtained from NiAl3 and Ni2Al3 were lower than those from nickel rich alloys (NiAl and Ni3Al). Especially, NiAl3 yielded the most active Raney-Ni cathode. This is because the fast aluminum leaching from NiAl3 phase gives large surface area of the electrode, the formation of small micropores, and the appearance of the Ni phase.
