英文摘要	magnesium borohydride-ethylenediamine composites (mg(bh4)(2)-neda, n = 2, 3, 4), a new type of hydrogen storage material, were synthesized by ball milling magnesium borohydride and ethylenediamine (eda). in particular, mg(bh4)(2).3eda and mg(bh4)(2).4eda can be well defined by a orthorhombic pbca cell and a triclinic p1 cell, respectively. hydrogen releasing from the mg(bh4)(2)-neda composites was observed at elevated temperatures. detailed dehydrogenation properties and mechanism of mg(bh4)(2)-2eda composite in which there are equivalent h delta+(n) and h delta-(b) were systematically investigated. ca. 8 wt% hydrogen can be evolved from mg(bh4)(2)-2eda in one step upon holding it at 260 degrees c for 12 h. mechanistic studies using phased dehydrogenation and isotopic labelling experiments show that hydrogen was released via the establishment of -n=b=n- bond as well as the combination of h delta+ (n) and h delta- (b). copyright (c) 2014, hydrogen energy publications, llc. published by elsevier ltd. all rights reserved.
