Abstract:
Ammonia borane (H 3 N-BH 3 , AB) is a lightweight material containing a high density of hydrogen (H 2 ) that can be readily liberated for use in fuel cell–powered applications. However, in the absence of a straightforward, efficient method for regenerating AB from dehydrogenated polymeric spent fuel, its full potential as a viable H 2 storage material will not be realized. We demonstrate that the spent fuel type derived from the removal of greater than two equivalents of H 2 per molecule of AB (i.e., polyborazylene, PB) can be converted back to AB nearly quantitatively by 24-hour treatment with hydrazine (N 2 H 4 ) in liquid ammonia (NH 3 ) at 40°C in a sealed pressure vessel.
