摘要 电沉积Ni-La合金上的阴极析氢行为刘淑兰,覃奇贤,成旦红,郭鹤桐(天津大学应用化学系天津300072)关键词Ni-La合金,电沉积,析氢反应在电解水制氢工业中,为降低能耗人们在研制电催化活性高的祈氢电极材料方面做了大量工作,主要有纯金属电极、合金电... Ni-La alloy coating containing 22.58wt%rare earth La was prepared by elec-trodeposition technique from aqueous solution.The results of XRD tests and calculationbased on the XRD spectra show that the Ni-La alloy coating obtained is a displacement solidsolution. Activation energy of cathodic hydrogen evolution reaction in alkaline solution andreal surface area of the Ni-La alloy and Ni electrodes were determined through electrochemi-cal tests. It is found from the results that the real surface area of the Ni-La allov electrode issubstantially larger than that of Ni electrode,Activation energy of cathodic hydrogen evolu-tion reaction in 25wt%NaOH solution of the Ni-La alloy electrode is enormously lower thanthat of Ni electrode.It can be concluded that the coating of electrodeposited rare earth alloyNi-La possesses excellent electrocatalytic activity for hydrogen evolution reaction.
