摘要：

The electrochemical adsorption-desorption of hydrogen on amorphous Ni40Nb60 is strongly alkaline media was investigated by cyclic voltammetry and chronopotentiometry. After cathodic polarization, the voltammogram in the -1.0 to -0.6 V range (vs. Hg/HgO) shows a new cathodic wave (C) and two anodic waves (A' and B'), due, respectively, to adsorption and desorption of H atoms at the surface of the alloy. The dependence of these waves on the sweep range and sweep potential is presented and discussed. The overpotential dependence on time at constant anodic current presents two plateaus, corresponding to the discharge of the two types of species on the surface of the alloy.
