摘要:

清潔能源的開發是緩解日益嚴峻的能源危機的關鍵，以氫能為代表的綠色二次能源正受到越來越多的關注。然而，安全、高效的氫氣儲運技術的缺失嚴重阻礙了氫能的規模化、實用化發展。在已報道的多種儲運氫技術中，固態儲氫因具有安全性高、儲氫密度高、操作壓力低等特點而成為研究的熱點和重點，尤其是輕金屬固態氫化物儲氫材料。但是，輕金屬氫化物較高的吸/放氫操作溫度與緩慢的吸/放氫速率阻礙了其實用化發展。盡管近年來有關優化金屬氫化物儲氫性能的報道層出不窮，但距離實用化仍有一定差距。微波、光、超聲、等離子體與電場等外場自提出以來，已經在化工、物理、材料等多個領域被廣泛研究。近年來，外場在儲氫領域的應用也逐漸獲得研究人員的關注并取得了重要進展，如對外場輔助制備儲氫材料、改善吸/放氫性能等方面已有廣泛研究。在儲氫系統中引入外場有望進一步提升材料儲氫的綜合性能，助力金屬氫化物儲氫技術邁向實用化。雖然外場在儲氫領域展現出一定的發展潛力和研究價值,但其反應機理和實際應用還有待進一步深入探索和研究。主要介紹近期有關外場應用在金屬氫化物儲氫體系中的作用機理和研究進展。

Abstract:

The development of novel clean energy is crucial to mitigating the increasingly severe energy crisis, and hydrogen energy, a secondary energy source, is drawing attention. However, safe and efficient means of storing and transporting hydrogen play-important roles in the scale-up of hydrogen energy. Among the reported storage and transportation technologies, solid-state hydrogen storage is the safest and it possesses high volumetric hydrogen capacity with low operating pressure. Light metal hydrides, in particular, are highly competitive in the field of hydrogen storages except for high operating temperature and slow reaction kinetics that has hindered their potential for wide application. Recently, external-fields such as microwave, light, ultrasound, plasma and electricity have gained attention in the field of hydrogen storage and made significant progress, for instance, in the fabrication of hydrogen storage materials and the improvement of their hydrogen absorption/desorption behaviors. The external field interaction with metal hydrides is promising and has attracted enormous research interest. In this paper, we will introduce some findings and development prospects of various external field applications in metal hydride hydrogen storage systems.
