Abstract

After treated by HF solution,the surface of Zr(V_0.2Mn_0.2Ni_0.54Mo_0.06)_2.4 alloy was transformed from Zr-rich and Mn-rich layer to Ni-rich layer. In this way, the nickel on thesurface could be believed to be the Raney-type nickel, which could obviously shorten the activation cycles, improve electrocatalytic activity and hydrogen adsorption ability. In this paper, the reaction mechanism on the alloy surface (i.e. the mechanism of nickel-catalysis, hydrogen-adsorption and hydrogen-transference) had been investigated. And the impedance spectra were fitted to an equivalentcircuit using a non-linear, least-squares (NLLS) fitting program.
