| 摘要: |
| 氢能的有效开发和应用主要需解决氢的安全、高效储运瓶颈问题。MgH2具有高储氢容量、资源丰富以及成本低廉等优点,被认为是最具发展前途的一类储氢材料。但是,MgH2较高吸放氢温度和较慢吸放氢速率限制了其实际应用。核壳结构纳米镁基储氢材料有助于材料储氢性能的改善,目前已取得了大量成果。本文针对国内外纳米镁基核壳结构储氢体系研究现状,归纳了该类储氢材料的制备方法,重点阐述和总结了其吸放氢热力学动力学性能、微观结构、物相变化,并对该领域的研究成果和方向进行了总结和展望,指出调控核壳结构镁基材料的纳米尺寸、添加高效纳米催化剂及其综合协同作用是镁基储氢材料领域未来的研究趋势和重要研究方向。 |

| Abstract: |
| The effective development and application of hydrogen energy requires solving the problem of efficient and safe hydrogen storage. MgH2 is regarded as one of the most prospective hydrogen storage materials due to its advantages of high energy density, favorable energy carrier, and low cost. High de/hydrogenation temperature and slow de/hydrogenation rate of MgH2, however, seriously restrict its practical storage applications. Core-shell nanostructured Mg-based hydrogen storage composite material is helpful to improve the hydrogen storage performance of the material, and has been investigated with a great number of achievements. This paper reviews the current research progress at home and abroad on core-shell nanostructured Mg-based materials for hydrogen storage, and the synthesis approaches for Mg-based hydrogen storage materials are classified. Moreover, the de/hydrogenation thermodynamic and kinetic properties, microstructures, and phase changes are emphatically discussed. Finally, the experimental results and the associated development and prospect of core-shell nanostructured Mg-based materials are summarized. It has been pointed out that regulating the nano-size of Mg-based materials, adding highly efficient catalysts, and focusing on their synthetic approaches are crucial future research trends and key research directions of the field. |
