Abstract

After treated by HF solution,the surface of Zr(V_(0.2)Mn_(0.2)Ni_(0.54)Mo_(0.06))_(2.4) alloywas 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 activationcycles,improve electrocatalytic activity and hydrogen adsorption ability.In this paper,the reactionmechanism on the alloy surface(i.e. the mechanism of nickel-catalysis,hydrogen-adsorption andhydrogen-transference)had been investigated.And the impedance spectra were fitted to an equivalentcircuit using a non-linear,least-squares(NLLS)fitting program.
