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.
