摘要:

固態(tài)儲(chǔ)氫具有體積密度高、儲(chǔ)運(yùn)方便、安全性好等優(yōu)勢(shì)，是目前最具發(fā)展前景的儲(chǔ)氫方式之一。開(kāi)發(fā)在低溫（<80 ℃）條件下具備可逆儲(chǔ)氫能力的氫化物對(duì)拓展固態(tài)儲(chǔ)氫技術(shù)的應(yīng)用具有重要意義。過(guò)渡金屬配位鋁氫化物的熱力學(xué)穩(wěn)定性較低，有可能滿足固態(tài)儲(chǔ)氫系統(tǒng)的低溫應(yīng)用要求，具有潛在的基礎(chǔ)研究和應(yīng)用價(jià)值。系統(tǒng)性介紹了過(guò)渡金屬配位鋁氫化物的研究進(jìn)展，包括氫化物的制備方法、結(jié)構(gòu)和性能表征以及儲(chǔ)氫機(jī)理等方面的研究動(dòng)態(tài)，并討論了其發(fā)展面臨的主要問(wèn)題和發(fā)展趨勢(shì)，為過(guò)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.
