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。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.
