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.

该提案的主要目标是开发新型化学/催化方法，以优化氨硼烷 (AB) 析出氢气的动力学和程度。 AB 代表了一种非常有前途的储氢材料（19.6 wt% 氢），通过应用两种互补方法（基于金属试剂的化学计量或催化开发）将显着推进其开发：（i）旨在破坏的化学修饰固态二氢键框架，从而促进 H2 更容易和完全的演化； (ii) AB 脱氢的过渡金属催化，特别关注机理信息的阐明，从而可以合理设计更有效的催化剂系统。
