摘要

This paper reports the synthesis of Mg_3La alloys with different hydrogenation degree through controlling the hydrogen amount introduced and reveals the hydrogenation mechanism. The hydrolysis rate and hydrogen yield of Mg_3La hydride could be controllable through adjusting the ratio of LaH_3 to Mg or MgH_2. The fully hydrogenated Mg_3La alloy can generate 873.24 ml g~(-1) in 66 min (7.80 wt.%). The results show that the hydrolysis performance of MgH_2 in Mg_3La hydrides could be significantly accelerated by LaH_3 while that of Mg was affected limitedly by LaH_3.
