摘　　要：氢能是一种理想的二次能源。氨硼烷(NH3BH3,AB)具有19.6%(wt,质量分数)的氢含量而受到广泛关注。氨硼烷热分解放氢具有放氢诱导期较长、有挥发性副产物等缺点。近年来,人们成功研究出几种促进氨硼烷热分解放氢,抑制副产物生成和经济、高效的氨硼烷再生技术。这些令人瞩目的技术为氨硼烷作为储氢材料应用于车载系统提供了广阔的前景。从这个角度,对近阶段氨硼烷的合成、热分解的改性和再生技术的研究进行了综述。Hydrogen energy is a kind of ideal secondary energy.Ammonia borane is attractived due to its high hydrogen content 19.6%（wt）.However,its practical application is greatly restricted by the concurrent release of volatile byproducts and a long induction period.Several strategies have been successfully developed for promoting H_2 release and for suppressing the evolution of volatile by-products from the solid-state thermolysis of AB.Several potentially cost-effective and energy-efficient routes for regenerating AB from the spent fuels have been experimentally demonstrated.These remarkable technological advances offered a promising prospect of using AB-based material as viable H_2 carriers for on-board application.In this perspective,the recent progress in synthesis of AB,in promoting H_2 release from the solid-state thermolysis of AB and in developing regeneration technologies were briefly reviewed.
