| 摘要: |
| Mg基材料由于具有高储氢量而被认为是一类存在良好应用前景的固态储氢材料,然而储氢动力学和热力学方面的缺陷限制了其应用步伐。已有研究表明,稀土元素及其化合物对提升Mg基材料的储氢性能具有显著效果。本文综述了有关稀土对Mg基材料储氢性能提升效果及其作用机制的研究进展。首先,概述了一系列稀土金属、稀土氢化物、稀土氧化物、稀土卤化物、稀土复合催化剂等稀土材料,对Mg基材料储氢量、储氢动力学、储氢热力学和储氢循环性能的影响；其次,深入探究了稀土添加剂影响Mg基材料吸氢和放氢过程的微观机理,重点关注稀土添加剂的晶体结构、微观形貌、化学价态演变规律,及其对Mg基材料储氢性能的影响机理；最后,总结了本领域存在的若干问题,提出了对应的建议,并展望未来的研究趋势。 |

| Abstract: |
| Mg-based materials are considered to be a type of solid-state hydrogen storage material with good application prospects due to their high hydrogen storage capacity. However, deficiencies in hydrogen storage kinetics and thermodynamics limit the pace of their application. Studies have shown that rare earth (RE) elements or compounds have a very significant effect on improving the hydrogen storage performance of Mg-based materials. This article reviews the research progress on the effect of rare earths on improving the hydrogen storage performance of Mg-based materials and their mechanism of action. Firstly, the effects of a series of rare earth metals, rare earth hydrides, rare earth oxides, rare earth halides, rare earth composite catalysts, etc., on the hydrogen storage capacity, hydrogen storage kinetics, hydrogen storage thermodynamics, and hydrogen storage cycle performance of Mg-based materials were summarized. Secondly, the mechanism of rare earth additives affecting the hydrogen absorption and hydrogen desorption process of Mg-based materials was explored, focusing on the crystal structure, micromorphology, chemical valence evolution rules of the rare earth additives, and their impact on the hydrogen storage performance of Mg-based materials. Finally, we also summarized the research progress and existing problems in this field, and looked forward to future research trends. |
