Regeneration of ammonia borane using hydrazine and ammonia from polyborazylene and spent AB

Abstract: Ammonia borane (AB) is a highly promising hydrogen storage material. Recently we have shown that combining AB with a polymer produces a material which has great potential for wide a range of commercial applications. In order to become a viable alternative to fossil fuels, it is important that effective recycling protocols are developed for the material. The most promising regeneration protocol reported to date involves treatment of polyborazylene (PB), which used as a surrogate for neat AB waste, with hydrazine in liquid ammonia. This process reportedly achieved almost quantitative yields of AB -up to 95%. We have attempted to replicate this procedure using real AB waste and have found that the protocol is much less effective. We hope to use neutron spectroscopy to gain an insight into the differences in the chemistry of PB and waste AB when treated under the regeneration conditions.
