用KOH、NaOH或LiOH溶液对LaNi 2.5Co 2.5进行预处理，分别诱导K、Na或Li的碱原子的渗透。这些碱性原子在合金表面上的存在降低了合金的电子的功函数超过1.1 eV与K原子。降低合金的电子功函数可以提高合金的电化学沉积速率。
The pretreatment of LaNi2.5Co2.5with KOH, NaOH or LiOH solution induces the penetration of the alkaline atom of K, Na or Li, respectively. The presence of these alkaline atoms on the alloy surface reduces the work function for electrons of the alloy over 1.1 eV with K atoms. The electrochemical hydriding rate can be enhanced by decreasing the work function for electrons of the alloy.
