摘要:: 非晶态合金是一类非平衡态材料，具有丰富的能量状态，并表现出多种亚稳特征，在很多方面展示出与晶态合金相比全新的性能。近年来，研究人员报道了一系列的新型Mg基非晶态储氢合金，与传统晶态Mg基储氢合金相比，非晶Mg基合金的原子结构均匀且化学成分范围广，因此具有更大的储氢性能调控空间。由于其长程无序的原子结构，部分Mg基非晶态合金还展示了更高的储氢量、更快的储氢动力学。对Mg基非晶态储氢合金的研究进展进行评述，首先讨论了非晶态合金在储氢方面的优势和不足，进而概括了Mg基非晶态储氢合金的常用制备方法，对其研究和应用进行评述，并介绍调控其储氢性能的新策略，最后总结并展望有关Mg基非晶态储氢合金的研究、应用和挑战。

Abstract:: Amorphous alloys are a group of non-equilibrium materials with abundant energy states and various metastable characteristics, exhibiting completely new properties compared with the crystalline alloys in many aspects. In recent years, researchers reported a series of new Mg-based amorphous alloys for hydrogen storage applications. Compared with the traditional crystalline Mg-based hydrogen storage alloys, amorphous Mg-based alloys have uniform atomic structures together with a wide range of chemical compositions, allowing large space for hydrogen storage performance regulation. Due to the long-range disordered atomic structure, some Mg-based amorphous alloys also exhibit higher hydrogen storage capacity and faster hydrogen storage kinetics. In this Review, the research progress of Mg-based amorphous hydrogen storage alloys is reviewed. First, the advantages and disadvantages of amorphous alloys in terms of hydrogen storage performance are discussed, and then the common preparation methods of Mgbased amorphous hydrogen storage alloys are summarized. The research and application of Mg-based amorphous hydrogen storage alloys are reviewed, and new strategies for regulating the hydrogen storage properties of Mg-based amorphous hydrogen storage alloys are introduced. Finally, the research, applications and challenges of Mg-based amorphous hydrogen storage alloys are summarized and prospected.
