Description:
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 degrees C in a sealed pressure vessel.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sutton, Andrew D -- Burrell, Anthony K -- Dixon, David A -- Garner, Edward B 3rd -- Gordon, John C -- Nakagawa, Tessui -- Ott, Kevin C -- Robinson, J Pierce -- Vasiliu, Monica -- New York, N.Y. -- Science. 2011 Mar 18;331(6023):1426-9. doi: 10.1126/science.1199003.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Chemistry Division, Los Alamos National Laboratory, Los Alamos, NM 87545, USA. adsutton@lanl.gov〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21415349" target="_blank"〉PubMed〈/a〉
