英文摘要	due to the coordinative nature of nh3 in the libh4 ammines, nh3 desorbs predominantly at temperatures below 180 degrees c under an open flow mode. interestingly, the emission of nh3 can be effectively suppressed in conjunction with improved hydrogen desorption properties by introducing a cobalt catalyst (co-catalyst) and heating the amines in a small closed vessel. under such condition, li(nh3)(n)bh4, where n = 1, 4/3, 2, releases ca. 15.3 wt%, 17.8 wt %, 14.3 wt% hydrogen at 250 degrees c, respectively. fairly high h-purity (99.99%) can be achieved in the co-catalyzed li(nh3)bh4 sample upon releasing over 15 wt% h-2 below 250 degrees c. as for the co-catalyzed li(nh3)(2)bh4 sample approximately 14.3 wt% of h-2 (h-purity: 97.60%) can be desorbed in a much improved reaction rate. copyright (c) 2015, hydrogen energy publications, llc. published by elsevier ltd. all rights reserved.
