| 摘 要： | 以LaNi5为代表的镧系储氢合金有优良的吸放氢性能,抗中毒能力强,因而受到广泛重视1]. 目前已开发出许多二元及多元镧系合金,并研究了部分合金的表面性质1～4],但结果并不一致. 本文制备了四元合金LaNi4Cu0.5Co0.5,通过X 射线光电子能谱(XPS)、扫描电镜(SEM)和吸氢测试等方法研究该合金的性质。

| Abstract: | A quarternary hydrogen storage alloy LaNi 4Cu 0.5 Co 0.5 was prepared using a coprecipitation reduction diffusion method. The alloy is activated easily. The surface species and composition of the alloy were derived from XPS measurements. SEM studies revealed many microcracks formed after activation, favoring rapid hydrogen absorption kinetics. |
