摘要:

非晶態(tài)合金是一類非平衡態(tài)材料，具有豐富的能量狀態(tài)，并表現(xiàn)出多種亞穩(wěn)特征，在很多方面展示出與晶態(tài)合金相比全新的性能。近年來，研究人員報道了一系列的新型Mg基非晶態(tài)儲氫合金，與傳統(tǒng)晶態(tài)Mg基儲氫合金相比，非晶Mg基合金的原子結(jié)構(gòu)均勻且化學(xué)成分范圍廣，因此具有更大的儲氫性能調(diào)控空間。由于其長程無序的原子結(jié)構(gòu)，部分Mg基非晶態(tài)合金還展示了更高的儲氫量、更快的儲氫動力學(xué)。對Mg基非晶態(tài)儲氫合金的研究進(jìn)展進(jìn)行評述，首先討論了非晶態(tài)合金在儲氫方面的優(yōu)勢和不足，進(jìn)而概括了Mg基非晶態(tài)儲氫合金的常用制備方法，對其研究和應(yīng)用進(jìn)行評述，并介紹調(diào)控其儲氫性能的新策略，最后總結(jié)并展望有關(guān)Mg基非晶態(tài)儲氫合金的研究、應(yīng)用和挑戰(zhàn)。

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�瞓ased 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.
