The primary objective of this proposal is the development of novel chemistry/catalysis to optimize the kinetics and extent of dihydrogen evolution from ammonia borane (AB). AB represents a very promising hydrogen storage material (19.6 wt % hydrogen), the exploitation of which will be significantly advanced by the application of two complementary approaches, based around either stoichiometric or catalytic exploitation of metal reagents: (i) chemical modification designed to disrupt the framework of dihydrogen bonding in the solid state and thereby facilitate more facile and complete evolution of H2; and (ii) transition metal catalysis of AB dehydrogenation, focussing in particular on the elucidation of mechanistic information, thereby allowing for the rational design of more efficient catalyst systems.

这项建议的主要目标是开发新的化学/催化剂，以优化氨基硼烷(AB)析氢的动力学和程度。AB是一种非常有前途的储氢材料(19.6wt%氢)，通过应用两种互补的方法，基于化学计量或催化开发金属试剂，将极大地促进AB的开发：(I)化学修饰，旨在破坏固态中的二氢键框架，从而促进氢气更容易和更完全的析出；以及(Ii)过渡金属催化AB脱氢，特别是专注于阐明机理信息，从而允许合理设计更有效的催化剂系统。
