摘　　要：采用电沉积方法在铜箔上制备了Ni-Fe-ZrO2复合电极。研究了纳米ZrO2微粒的质量浓度、电流密度、温度、电沉积时间等工艺参数对复合电极析氢性能的影响。结果表明:在纳米ZrO2微粒10g/L,电流密度25mA/cm2,温度40℃,电沉积时间40min的条件下,可制备出具有最佳析氢性能的Ni-Fe-ZrO2复合电极。其析氢电位大于Ni-Fe合金电极的。Ni-Fe-ZrO2 composite electrode was prepared on copper foil surface by electrodeposition. Effects of ZrO2 nano-particle mass concentration, current density, temperature and electrodeposition time on the hydrogen-evolution performance of composite electrode were studied. Results showed that the Ni-Fe-ZrO2 composite electrode with optimal hydrogen- evolution performance can be prepared under the conditions of ZrO2 nano-particle 10 g/L, current density 25 mA/cm2, temperature 40 ℃ and electrodeposition time 40 min. The hydrogen- evolution potential was larger than that of Ni-Fe alloy electrode.
