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. |
