| Abstract: | The nanocrystalline nickel molybdenum cobalt alloy deposits were obtained by electrodeposition method. The structures of the deposits were analyzed by XRD and XPS; considerable lattice deformation in alloy occured and only one diffraction peak was recorded on XRD spectrum. The XPS results of nanocrystalline Ni Mo Co deposit indicated that the nickel and molybdenum and cobalt coexist in metal state of the deposits, with binding energy being increased in some extent. The nanocrystalline Ni Mo Co alloy deposit electrode offered better electrocatalytic hydrogen evolution than nanocrystalline Ni Mo alloy electrode. The electrochemical impedance spectra of the nanocrystalline Ni Mo Co alloy electrode indicated that hydrogen evolution in 30%( m/m ) KOH follows Volmer Tafel mechanism at lower potential, but at higher potential it follows Volmer Heyrovsky mechanism. |
