摘要:

清潔能源的開(kāi)發(fā)是緩解日益嚴(yán)峻的能源危機(jī)的關(guān)鍵，以氫能為代表的綠色二次能源正受到越來(lái)越多的關(guān)注。然而，安全、高效的氫氣儲(chǔ)運(yùn)技術(shù)的缺失嚴(yán)重阻礙了氫能的規(guī)模化、實(shí)用化發(fā)展。在已報(bào)道的多種儲(chǔ)運(yùn)氫技術(shù)中，固態(tài)儲(chǔ)氫因具有安全性高、儲(chǔ)氫密度高、操作壓力低等特點(diǎn)而成為研究的熱點(diǎn)和重點(diǎn)，尤其是輕金屬固態(tài)氫化物儲(chǔ)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(shí)用化發(fā)展。盡管近年來(lái)有關(guān)優(yōu)化金屬氫化物儲(chǔ)氫性能的報(bào)道層出不窮，但距離實(shí)用化仍有一定差距。微波、光、超聲、等離子體與電場(chǎng)等外場(chǎng)自提出以來(lái)，已經(jīng)在化工、物理、材料等多個(gè)領(lǐng)域被廣泛研究。近年來(lái)，外場(chǎng)在儲(chǔ)氫領(lǐng)域的應(yīng)用也逐漸獲得研究人員的關(guān)注并取得了重要進(jìn)展，如對(duì)外場(chǎng)輔助制備儲(chǔ)氫材料、改善吸/放氫性能等方面已有廣泛研究。在儲(chǔ)氫系統(tǒng)中引入外場(chǎng)有望進(jìn)一步提升材料儲(chǔ)氫的綜合性能，助力金屬氫化物儲(chǔ)氫技術(shù)邁向?qū)嵱没�。雖然外場(chǎng)在儲(chǔ)氫領(lǐng)域展現(xiàn)出一定的發(fā)展?jié)摿�和研究�(jī)r(jià)值,但其反應(yīng)機(jī)理和實(shí)際應(yīng)用還有待進(jìn)一步深入探索和研究。主要介紹近期有關(guān)外場(chǎng)應(yīng)用在金屬氫化物儲(chǔ)氫體系中的作用機(jī)理和研究進(jìn)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.
