摘要:

固態(tài)儲氫具有體積密度高、儲運方便、安全性好等優(yōu)勢，是目前最具發(fā)展前景的儲氫方式之一。開發(fā)在低溫（<80 ℃）條件下具備可逆儲氫能力的氫化物對拓展固態(tài)儲氫技術(shù)的應用具有重要意義。過渡金屬配位鋁氫化物的熱力學穩(wěn)定性較低，有可能滿足固態(tài)儲氫系統(tǒng)的低溫應用要求，具有潛在的基礎研究和應用價值。系統(tǒng)性介紹了過渡金屬配位鋁氫化物的研究進展，包括氫化物的制備方法、結(jié)構(gòu)和性能表征以及儲氫機理等方面的研究動態(tài)，并討論了其發(fā)展面臨的主要問題和發(fā)展趨勢，為過渡金屬配位鋁氫化物的深入研究提供參考。

Abstract:

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.
