The utilization of hydrogen in safety conditions is crucial for the development of a hydrogen-based economy. Among all methodologies, solid-state hydrogen release from ammonia borane through thermal stimuli is very promising due to the high theoretical hydrogen release. Generally, carbonaceous or inorganic matrices have been used to tune the reactivity of ammonia borane. Nevertheless, these solutions lack chemical tunability, and they do not allow one to properly tune the complex chemical pathway of hydrogen release from ammonia borane. In this study, we investigated the effect of a bioderived multifunctional polymeric matrix on hydrogen release from ammonia borane, reaching pure hydrogen release of 1.2 wt.% at 94 °C. We also describe new chemical pathways involving the formation of anchored intermediates, namely BxNy species.
在安全条件下利用氢气对于氢基经济的发展至关重要。在所有方法中，通过热刺激从氨硼烷中固态释放氢气由于其高理论氢释放量而非常有前景。一般来说，碳质或无机基质已被用于调节氨硼烷的反应性。然而，这些解决方案缺乏化学可调性，并且不允许人们适当地调节从氨硼烷中释放氢气的复杂化学途径。在本研究中，我们研究了一种生物衍生的多功能聚合物基质对氨硼烷氢释放的影响，在94℃时达到了1.2 wt.%的纯氢释放。我们还描述了涉及形成锚定中间体（即BxNy物种）的新化学途径。
