Abstract Ni10Mo/Cu foam (CF) electrode was prepared by electrochemical depositing the Ni10Mo film on CF. Ni10Mo/CF electrodes with different Ni10Mo contents and particle sizes were obtained by changing the deposition time, the surface morphology and electrochemical hydrogen evolution reaction (HER) performance of Ni10Mo/CF electrodes were also explored. The morphology of Ni10Mo alloy nanoparticles was studied by SEM analysis, and the composition of Ni10Mo was studied by EDS and XRD analysis. The electrochemical activity of the electrodes was comprehensively evaluated by linear scanning voltammetry (LSV), testing electrochemical double-layer capacitance, and stability tests. The results show that the morphology of the catalysts depends on the deposition time. With the increase of the deposition time, the HER catalytic activity of Ni10Mo alloy nanoparticles in 1 M KOH increases first and then decreases, when the current density remain the same. Among them, when the deposition time is 6 min, the electrode shows an overpotential of 227 mV at 10 mA/cm2 and exhibits excellent stability.
