摘要:

鎂（含鎂）系儲氫材料作為固態儲氫技術的工作介質，具有高重量儲氫密度和高體積儲氫密度的突出優勢，但其吸/放氫溫度高、速率慢、可逆性差等難點問題一直沒有得到有效解決，嚴重阻礙了其實際應用。按照化學鍵性質的區別，鎂（含鎂）系儲氫材料可分為合金和配位化合物兩大類。過去幾十年的研究工作主要集中在通過改變成分和結構、加入摻雜（催化）劑、構建微納結構和失穩體系等手段來解決這些問題。但從實際效果上來看，在改善動力學方面的進展要大于熱力學方面，使用鎂（含鎂）系儲氫材料的過程中仍需要通過傳統電加熱的方式提供額外能量，以克服吸/放氫反應的熱力學和動力學能壘，這導致了能量轉化效率降低。最新的研究表明，通過直接或間接地利用非電加熱形式（太陽能和工業余熱）的外場能量，有望解決能效低的問題，為鎂（含鎂）系儲氫材料的實際應用帶來新曙光。回顧了鎂（含鎂）系儲氫材料的研發歷程，闡述了各階段取得的標志性進展，分析和探討了今后的研究方向。

Abstract:

Magnesium-based (or magnesium-containing) materials are the promising solid hydrogen storage mediums due to the high gravimetric and volumetric hydrogen storage density. However, the high operation temperature, slow kinetics, and capacity decay severely limit their practical application. Based on the differences in chemical bonding, magnesium-based (or magnesium�瞔ontaining) storage materials are divided into alloys and coordination compounds. Over the past decades, much research has been undertaken to address the above mentioned issues through adjusting composition/structure, doping catalyst, micro-nanosizing and combing with other hydrides, resulting in significant improvements in kinetics rather than thermodynamics. Therefore, extra electric heating is still required to facilitate hydrogenation/dehydrogenation, which causes the low energy efficiency.Recent research focused on non-electrical heating energy, such as solar energy and waste heat, either directly or indirectly, providing new possibilities for the practical application of magnesium-based (or magnesium�瞔ontaining) hydrogen storage materials. This paper reviews the development of magnesium-based (or magnesium-containing) hydrogen storage materials and the milestones at each stage. Furthermore, the research direction is analyzed and discussed.
