| 摘 要： | 采用电沉积法制备Ni-Mo合金电极,通过测定电极在30%KOH溶液中的阴极极化曲线,研究不同沉积条件(钼盐浓度、pH值、沉积电流密度、沉积温度)对镀层析氢性能的影响,并用XRD、SEM对镀层进行了表征。结果表明:所获得的镀层为纳米晶结构,镀层表面颗粒分布均匀且具有很大的比表面积。通过正交实验确定了最佳电沉积工艺条件:钼盐浓度32 g/L,pH值8.0,沉积电流密度22 A.dm-2,温度50℃。最佳工艺条件制备出的Ni-Mo合金电极的析氢过电位仅为68 mV,比纯Ni电极降低348 mV。

| Abstract: | In this paper,we prepare the Ni-Mo alloy electrode by electrodepositing.The effect of the prepare conditions,such as the concentration of main salt,deposition current density,pH and temperature were investigated.Before researching the prepare condition of Ni-Mo alloy,the HER activity was discovered by steady state polarization curve,the structure and appearance of the coatings was observed by SEM and XRD.It was found that the roughness of Ni-Mo alloy become more obvious and the structure is nanocrystalline.... |
