The research and development of new high capacity hydrogen storage materials is of both academic significance and practical importance. LiBH₄ has been attracting extensive attention because of its high gravimetric and volumetric hydrogen contents, but its practical applications are hindered by high thermal stability, sluggish kinetics, and relatively high operating temperatures. Doping with catalysts is a key strategy and important research direction to solve these problems. Here, various catalysts and their performances in the dehydrogenation of LiBH₄ are summarised. The catalytic mechanisms of different catalysts are also outlined. In addition, NH₃BH₃ has been drawing much attention due to its high hydrogen capacity and environmental friendliness. Release of hydrogen from NH₃BH₃ by hydrolysis can proceed at room temperature with appropriate catalysts. The effects of diverse catalysts on the hydrogen evolution of NH₃BH₃ hydrolysis are also reviewed. Some prospective aspects for research and development of hydrogen storage materials are also proposed in this review.

催化剂改善了LiBH ₄和NH ₃ BH ₃的储氢能力

新型高容量储氢材料的研究具有重要的学术意义和现实意义。LiBH _4的重量和体积氢含量很高，因此受到了广泛的关注，但是其实际应用受到高热稳定性，缓慢的动力学和相对较高的工作温度的限制。催化剂的掺杂是解决这些问题的关键策略和重要的研究方向。在此，总结了各种催化剂及其在LiBH ₄脱氢中的性能。还概述了不同催化剂的催化机理。此外，NH ₃ BH ₃由于其高氢气容量和环境友好性，一直备受关注。在适当的催化剂下，可以在室温下通过水解从NH ₃ BH ₃释放氢。本文还综述了各种催化剂对NH ₃ BH ₃水解过程中氢释放的影响。本文还对储氢材料的研究和开发提出了一些展望。
