英文摘要Hydrogen Storage is one of the pending and challenging technical barriers in the implementation of hydrogen energy.1.2 Amide-hydride and ammonia borane are the two systems attracting considerable attention. It has been demonstrated that 5.5 wt.% or 6.7 wt.% of hydrogen can be reversibly or irreversiblly stored in magnesium amide-lithium hydride and ammonia borane systems, respectively.3.4 However, relatively high operating temperatures due to kinetic barriers place serious restriction onto the application of those substances. Conventional transition metals have little catalytic effect on the dehydrogenation of the amide-hydride complexes. Interestingly, K works well for Mg(NH2)2-LiH systems.5 For the decomposition of ammonia borane, the dissociation of B-H bond is the first step to be involved, where transition metal borides can effectively enhance the dehydrogenation rate6. The details of the kinetic improvement and the identification of reactive species will be presented.; Hydrogen Storage is one of the pending and challenging technical barriers in the implementation of hydrogen energy.1.2 Amide-hydride and ammonia borane are the two systems attracting considerable attention.
