摘要

A simple method was developed for improving the hydrogen storage properties through adding nano Ni-Al compounds using as a stable catalyst to the La₂Mg₁₇ alloys by a PVD method. With the trace addition of the catalyst, hydrogen absorption and desorption rate are all substantially improved for the La-Mg based alloys. The alloys formation process has been determined, and the activity energy of the hydride dehydrogenation reaction before and after Ni-Al nanocrystalline addition was also calculated.
