过渡金属配位铝氢化物的研究进展

Research Progress of Transition Metal Alanates

固态储氢具有体积密度高、储运方便、安全性好等优势,是目前最具发展前景的储氢方式之一。开发在低温(<80℃)条件下具备可逆储氢能力的氢化物对拓展固态储氢技术的应用具有重要意义。过渡金属配位铝氢化物的热力学稳定性较低,有可能满足固态储氢系统的低温应用要求,具有潜在的基础研究和应用价值。系统性介绍了过渡金属配位铝氢化物的研究进展,包括氢化物的制备方法、结构和性能表征以及储氢机理等方面的研究动态,并讨论了其发展面临的主要问题和发展趋势,为过渡金属配位铝氢化物的深入研究提供参考。

Solid-state hydrogen storage materials have been considered as one of the most promising hydrogen storage methods due to the advantages of high volumetric density, flexible transportation, good safety, etc. The development of hydrides with reversible hydrogen capability at low temperature(<80 ℃) is of great significance for expanding the application of solid-state hydrogen storage technology. The low thermodynamic stability of transition metal alanates may meet the low-temperature requirements of hydrogen storage systems, which has the potential values of fundamental research and applications. This paper not only systematically reviews the research progress of transition metal alanates, including the preparation methods, structural and property characterizations, underlying mechanisms, etc., but also discusses the main problems and development trend, which aims to provide reference for the further study of transition metal alanates.
