摘要：

The hydrogen evolution reactions on porous Ni3Al electrodes, as well as their electrochemical properties in 6 M KOH solutions have been investigated by the polarization measurement, cyclic voltammetry and EIS technique. Results show that the porous Ni3Al electrodes with lower pore size possess higher catalytic activity for hydrogen evolution in KOH solutions. Their stability in 6 M KOH at 298 K and 358 K under the condition of the reverse polarization is shown to be very good. The electrodes exhibit long term stability and retain high catalytic performance under industrial conditions. (C) 2013 Elsevier B.V. All rights reserved.
