摘要

This paper reports the synthesis of Mg3La alloys with different hydrogenation degree through controlling the hydrogen amount introduced and reveals the hydrogenation mechanism. The hydrolysis rate and hydrogen yield of Mg3La hydride could be controllable through adjusting the ratio of LaH3 to Mg or MgH2. The fully hydrogenated Mg3La alloy can generate 873.24 ml g(-1) in 66 min (7.80 wt.%). The results show that the hydrolysis performance of MgH2 in Mg3La hydrides could be significantly accelerated by LaH3 while that of Mg was affected limitedly by LaH3. (C) 2013 Elsevier B.V.
