Research Progress of Complex Hydrogen Storage Materials with Al–H Bond

摘要:

随着化石燃料等不可再生资源的日益紧缺和环境污染日益加重，人们迫切需要寻找替代能源。氢能作为可持续、清洁的能源而被广泛研究，其中氢的储运问题成为氢能应用的关键。含Al–H键络合物储氢材料由于具有较高的储氢量，成为近年来国内外储氢材料研究的热点。本文主要介绍了碱金属、碱土金属以及其它一些金属-铝氢化物等含Al–H键络合物储氢材料的成分、制备、晶体结构以及储氢性能的最新研究进展。

Abstract:

Owing to the exhaustion of non-renewable resources such as fossil fuels and the increasing seriousness of environmental pollution, it is urgent to find alternative energy. Hydrogen energy has been extensively studied for its cleanness and sustainability. An important issue for the utilization of hydrogen energy is the hydrogen storage and transportation. The complex hydrogen storage materials with Al–H bond have been regarded as promising materials for hydrogen storage due to its large hydrogen storage capacity. This paper mainly introduced the new research progress of the composition, preparation, crystal structure and hydrogen storage properties of several kinds of complex hydrogen storage materials with Al–H bond, such as alkali metal, alkaline-earth metal and some other metal-aluminum hydrides.
