摘　　要：氢能的利用越来越受到人们的重视,而氢的储存和运输限制了其广泛的实际应用。镁基合金作为一种固体储氢材料,在储氢领域显示出巨大的潜力。但是,吸放氢温度高,释氢速率慢,阻碍了其工程应用。为了提高镁基合金的储氢能力,目前的研究主要集中在合金成分的优化和加工工艺的改进方面,而纳米细化是最有前途的方法之一。详细介绍了纳米镁的各种制备工艺,包括高能球磨、物理气相沉积、氢化化学气相沉积、液相化学合成和模板法,并分析了各种方法的优缺点。阐述了纳米结构和元素掺杂对镁基合金储氢性能的影响。本研究为储氢领域的材料开发和制备工艺的改进提供参考。The utilization of hydrogen energy has attracted great attention, while the storage and transportation of hydrogen restrict its wide practical application. As a solid hydrogen storage material, Mg-based alloys show great potential in the field of hydrogen storage. However, the high temperature of hydrogen absorption and release, and the slow rate of hydrogen release cast a shadow on its engineering application. To improve the hydrogen storage capacity of Mg-based alloys, the researches mainly focus on the optimization of alloy composition and the improvement of processing technology, and nano refinement is one of the most promising methods. In this study, all the processing technologies of nanostructured Mg are introduced, including high energy ball milling,physical vapor deposition, hydriding chemical vapor deposition, liquid-phase chemical synthesis and template method. The advantages and disadvantages of each method are also analyzed. The effect of nanostructure and element doping on the hydrogen storage property of Mg-based alloys is summarized. This study provides a reference for the research of the material development and improvement of preparation technology in hydrogen storage field.
