    摘要:

    鎂基儲(chǔ)氫材料由于價(jià)格低廉、儲(chǔ)氫量高和安全性好等優(yōu)點(diǎn)，受到人們的廣泛關(guān)注。然而較高的吸放氫溫度和較慢的動(dòng)力學(xué)性能在一定程度上限制了其在儲(chǔ)氫方面的進(jìn)一步研究和應(yīng)用。目前，該體系的研究熱點(diǎn)主要集中在優(yōu)化不同的改性方法，目的是得到低成本、大批量、小顆粒和穩(wěn)定性高的納米MgH2，并已取得了一定的進(jìn)展；但要獲得能夠在環(huán)境溫度下具有理想熱力學(xué)性能和實(shí)際應(yīng)用價(jià)值的鎂基儲(chǔ)氫材料，仍面臨巨大挑戰(zhàn)。本文中，我們總結(jié)了鎂基合金儲(chǔ)氫材料的研究進(jìn)展，并進(jìn)一步梳理了文獻(xiàn)中關(guān)于優(yōu)化和改變熱力學(xué)和動(dòng)力學(xué)性能的方法，為獲得具有高容量、低成本、吸放氫動(dòng)力學(xué)和熱力學(xué)性能優(yōu)異的鎂基儲(chǔ)氫材料提供更好的實(shí)驗(yàn)經(jīng)驗(yàn)和理論支持。

    Abstract:

    Mg-based hydrogen storage materials have attracted much attention because of their low price, high hydrogen storage capacity and fine safety. However, its higher temperature of hydrogen absorption and desorption and slow kinetic properties limit its further research and application in hydrogen storage. Recent research mainly focus on exploring different modification methods to obtain low cost, large quantities, small particles and high stability of MgH2 nanopowders, and some progress has been made; However, it is still a great challenge to obtain magnesium-based alloy hydrogen storage materials which have ideal thermodynamic properties and practical application value at ambient temperature. In this review, we summarized recent progress in the research on magnesium-based alloy hydrogen storage materials, and further categorized reported methods on changing thermodynamic and kinetic properties of magnesium-based alloy, to provide better empirical and theoretical support for obtaining magnesium-based hydrogen storage materials with high capacity and excellent kinetic & thermodynamic properties in hydrogen adsorption & desorption.
