Raney-nickel (Ni) cathodes were prepared on nickel wire from aluminum powder and titanium hydride powder by heat-treatment. The influence of the addition of titanium to the Raney-Ni electrode on the polarization characteristics of the hydrogen evolution reaction was studied in 1 M NaOH at 303 K. Although the coated layer was composed of nickel with a small amount of aluminum and titanium, the titanium was enriched the most. The relative surface area of the Raney-Ni cathodes was about 3500 independent of the presence of titanium, but titanium could decrease the hydrogen overpotential.
