摘要

氢具有高化学性、环保性和可再生性，是一种理想的能源载体，然而氢储存是制约氢能发展的主要瓶颈之一。为了实现安全、高效储氢，以镁合金为代表的固态储氢材料因储氢容量高、低成本被认为是最有前景的储氢材料之一。然而，由于镁氢化反应动力学缓慢、热力学稳定性高，镁基储氢合金的吸/脱氢温度高、吸氢率低等问题，阻碍了其实际应用。近年来，在镁基储氢材料的热/动力学改性方面已经取得了大量的成果，重点阐述合金化、纳米/非晶化、添加催化剂、复合化和薄膜等主要方法的最新进展；同时，对镁基储氢动力学研究现状进行总结，并提出未来发展方向。

Abstract

Hydrogen is an ideal energy carrier because of its high chemical

environmental protection and renewable properties. How to storage hydrogen is one of the largest limits that restrain the hydrogen energy development. In order to realize safe and efficient hydrogen storage

solid hydrogen storage materials represented by magnesium alloy are considered as one of the most promising hydrogen storage materials due to their high hydrogen storage capacity and low cost. However

the problems such as slow hydride reaction kinetics behavior and high thermodynamic stability

high hydrogen absorption/desorption temperature and low hydrogen absorption rate

hindered the application of magnesium based alloys. In recent years

a lot of achievements have been made in thermal/kinetic modification of magnesium-based hydrogen storage materials. This paper focuses on the recent progress of alloying

nano/amorphous

catalyst addition

compound and thin film. Furthermore

the research status of magnesium-based hydrogen storage kinetics is summarized

and the possible development direction in the future is proposed.
