摘要
Mg基储氢合金储量丰富、价格低、具有较高的储氢容量且环保无污染,是一种很有发展前景的储氢材料。但是该类合金吸放氢动力学性能差、吸放氢温度高,氢化物稳定不易分解,这些缺点使其应用受到一定限制。通过在Mg基储氢合金中进行元素替代或催化掺杂可以达到改善性能的作用。其中,在Mg基储氢合金中掺杂氧化物改善合金储氢性能的研究工作引起广泛关注。本文系统地分析总结了近年来在Mg基储氢合金中掺杂氧化物改善储氢性能的研究成果,对于开发具有商业价值的镁基储氢材料具有一定指导意义。
Mg-based hydrogen storage alloy is one of the most promising hydrogen storage material because of abundant reserves,low price,high hydrogen storage capacity and environmental protection. However,it is far from practical applications due to its poor kinetics properties,higher temperature and stable hydride in the hydriding/dehydriding process. The performance can be improved by elements substitution or catalytic doping in alloys. The study of improving hydrogen storage properties in Mg-base alloy has attracted wide attention. In this paper,researches on improving properties of Mg-based hydrogen storage alloys by doping oxides in recent years are summarized,which has a certain guiding significance for developing Mg-based hydrogen storage materials with commercial value.
