Abstract: Disclosed herein provide compositions and hydrogen release methods for a high-capacity complex hydrogen storage material. The hydrogen storage material is mainly composed of metal borohydride and NH3. The invention advantageously adopt ammonia, one cheap and easily supplied material with high hydrogen content (17.6 wt %), as one of the hydrogen source, offering a safe and efficient way to store hydrogen and release hydrogen. Furthermore, the hydrogen storage material can be further catalyzed by a transition metal catalyst to improve the dehydrogenation kinetics. With the addition of catalyst, 0.2-10 equiv. H2 could be evolved at ?100˜600° C., which might be applied on vehicles which are fueled by hybrid or fuel cell.
