英文摘要	Nano porous Ni, Ni-Mo and their oxides electrode materials were prepared by rapid solidification and de alloying. The phase, morphology and pore size distribution of porous electrode materials were characterized by XRD, SEM, TEM and N-2 absorption-desorption test, and the electro-catalytic hydrogen evolution of porous electrode was tested by linear scanning voltammetry, Tafel slope and chronopotentiometry. The results show that the hydrogen evolution activity of Ni-Mo alloy was the strongest and the process of hydrogen evolution is controlled by Volmer-Heyrovsky step. Its apparent exchange current density (j(0)) was 0.25 mA . cm(-2). After electrolyzing 10 000 seconds at constant current density (100 mA . cm(-2)), hydrogen evolution over-potential increased only by 39 mV, showing excellent hydrogen evolution stability. The improvement of specific surface area and intrinsic catalytic activity of Ni-Mo alloy electrode resulted in lower hydrogen evolution over-potential.
