*Nickel-based alloys (Ni0.8CoO0.1Zn0.05MnO0.02Ti0.01Y0.01Al0.01(M1), NiO0.8CoO0.1Zn0.05MnO0.02Ti0.01Y0.01Al0.01 (M2) and NiO0.6CoO0.35Zn0.025Ti0.025 (M3)) were synthesized from high purity powders by means of high-energy mechanical milling. The hydrogen evolution reaction (HER) kinetic-performance of the as-prepared materials was evaluated using linear sweep voltammetry at alkaline conditions and room temperature. According to kinetic parameters calculated from Tafel slopes, the sample M2 showed the better activity in the HER. These results suggest that the electrode surface state in the material play an important role in the proton-adsorption kinetic as demonstrated by SEM, open circuit potential transients and cyclic voltammetry techniques.
