“…[3][4][5][6] Ammonia borane (AB, NH 3 BH 3 ) is a typical representative of chemical hydrogen storage materials with a theoretical hydrogen storage capacity of 19.6 wt%, regarded as the compound with the highest hydrogen content found up to now. 7,8 AB can exist in the solid state under the atmospheric environment, with the unique physicochemical properties such as nontoxicity, incombustiblity, no corrosion and no explosion so on. Moreover, AB can release hydrogen gas (H 2 ) in a controllable manner via catalytic hydrolysis or alcoholysis, which is thus considered as an ideal hydrogen storage medium for fuel cells.…”
