Ammonia borane as an efficient and lightweight hydrogen storage medium

Ammonia borane (NH3BH3, AB) containing 19.6 wt% hydrogen has been considered as a promising candidate for on-board hydrogen storage applications on the way to the ideal "hydrogen economy". Whereas, how to control the energy of the hydrogen releasing and recycling of AB efficiently is the present challenge for its wide use. In this mini review, we highlight the preparation, dehydrogenation and regeneration of AB and briefly discuss the current developments, problems and feasible solutions in AB hydrogen storage chemistry.
