英文摘要	a series of mixtures of liab/libh4 with different molar ratios were prepared and their hydrogen storage properties were investigated in this study. among them, a new structure was found in the liab/libh4 sample with a molar ratio of 1/1. it is of orthorhombic structure and composed of alternative layers of liab and libh4. it shows similar hydrogen desorption behaviors of liab-libh4 and liab-0.5libh(4). for use in hydrogen storage, high hydrogen capacity and low operation temperature are demanded, thus, the dehydrogenation properties of liab-0.5libh(4) were subsequently measured. three steps of desorption were observed during the heating process, with a total release of 11.5 wt% h-2 at 500 degrees c. the reaction path was identified using a combined investigation of xrd and b-11 solid state nmr. dehydrogenation idnetic analyses show that the complex has lower activation energy (61 +/- 4 kj mol(-1) h-2) than that of liab (71 +/- 5 kj mol(-1) h-2). it is likely that dehydrogenation process was promoted due to the presence of libh4. copyright (c) 2013, hydrogen energy publications, llc. published by elsevier ltd. all rights reserved.
