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.

Journal of Electrochemistry
in this paper, Raman spectra, photocurrent and the UV-VIS reflectance aremeasured for studying the α-Fe_2O_3ultrafine particles adsorbed on Pt electrode. The blue shifts ofRaman peaks demonstrate the size quantization effect for the particles of 50 nm in diameter ascompared with the bulk material. With the changing of the potential , the photocurrent decrcases as theUV-VIS reflectance increases, and vice-versa. Therefore, the potential not only affects the hargetransfer direcdtion in the interface of electrede/redox couple, but also influences the light absortion onthe surface of particles.According to the results of photoelectrochemistry, we suggest that the cathedicphotocurrent in the potential range of more …
