采用极化曲线、循环伏安和交流阻抗技术研究了多孔Ni3Al电极在6M KOH溶液中的析氢反应及其电化学性能。结果表明，孔径较小的多孔Ni3Al电极在KOH溶液中具有较高的析氢催化活性。在反向极化条件下，它们在298 K和358 K的6 M KOH中的稳定性非常好。该电极具有长期稳定性，并在工业条件下保持高催化性能。
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.
