Hydrogen storage is still one of the most significant issues hindering the development of a "hydrogen energy economy". Ammonia borane is notable for its high hydrogen densities. For the material, one of the main challenges is to release efficiently the maximum amount of the stored hydrogen. Hydrolysis reaction is a promising process by which hydrogen can be easily generated from this compound. High purity hydrogen from this compound can be evolved in the presence of solid acid or metal based catalyst. The reaction performance depends on the morphology and/or structure of these materials. In this review, we survey the research on nanostructured materials, especially porous materials for hydrogen generation from hydrolysis of ammonia borane.
储氢仍然是阻碍“氢能经济”发展的最重要问题之一。氨硼烷因其高氢密度而备受关注。对于这种材料，主要挑战之一是有效地释放储存的最大量氢气。水解反应是一种很有前景的方法，通过该方法可以很容易地从这种化合物中产生氢气。在固体酸或金属基催化剂存在的情况下，可以从这种化合物中释放出高纯度氢气。反应性能取决于这些材料的形态和/或结构。在这篇综述中，我们概述了关于纳米结构材料，特别是用于氨硼烷水解制氢的多孔材料的研究。
