“…Magnesium and Mg-based hydrogen storage materials are considered to be promising materials for hydrogen storage in gaseous and electrochemical applications due to their high hydrogen storage capacity (7.6 wt.% for pure Mg), light weight and low cost [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. However, their practical application for hydrogen storage has been limited because of their high working temperature and sluggish absorption/desorption kinetics.…”

“…Therefore, Mg-Ni alloy film is the most studied among all kinds of 098801-6 Mg alloy films. [122][123][124][125][126] Ouyang et al [127][128][129] reported hydrogen storage properties of multilayer Mg-Ni thin film capped with Pd or MmM 5 . For MgNi/Pd multilayer with the total thickness of 1.7 µm, the hydrogen absorption content reached 4.6 mass% at room temperature and the hydrogen desorption reached 3.4 mass%.…”

Mg-based hydrogen storage materials are considered to be one of the most promising solid-state hydrogen storage materials due to their large hydrogen storage capacity and low cost. However, slow hydrogen absorption/desorption rate and excessive hydrogen absorption/desorption temperature limit the application of Mg-based hydrogen storage materials. The present paper reviews the advances in the research of Mg-based hydrogen storage film in recent years, including the advantage of the film, the function theory of fabricating method and its functional theory, and the influencing factors in the technological process. The research status worldwide is introduced in detail. By comparing pure Mg, Pd-caped Mg, non-palladium capped Mg, and Mg alloy hydrogen storage films, an ideal tendency for producing Mg-based film is pointed out, for example, looking for a cheap metal element to replace the high-priced Pd, compositing Mg film with other hydrogen storage alloy of catalytic elements, and so on.

“…To improve the hydrogenation properties of Mg, Wang and Ouyang et al prepared Mg–Ni thin films, and Mg/MmM x and Mg-Ni/MmM 5 multi-layer films [ 69 , 70 , 71 , 72 , 73 , 74 ]. They prepared the Mg/MmM 5 multi-layer film via magnetron sputtering, and X-ray diffraction (XRD) analysis showed that most of the Mg was hydrogenated and dehydrogenated at about 523 K, which is about 100 K lower than the dehydrogenation temperature of pure Mg film.…”

Mg-based hydrides are one of the most promising hydrogen storage materials because of their relatively high storage capacity, abundance, and low cost. However, slow kinetics and stable thermodynamics hinder their practical application. In contrast to the substantial progress in the enhancement of the hydrogenation/dehydrogenation kinetics, thermodynamic tuning is still a great challenge for Mg-based alloys. At present, the main strategies to alter the thermodynamics of Mg/MgH2 are alloying, nanostructuring, and changing the reaction pathway. Using these approaches, thermodynamic tuning has been achieved to some extent, but it is still far from that required for practical application. In this article, we summarize the advantages and disadvantages of these strategies. Based on the current progress, finding reversible systems with high hydrogen capacity and effectively tailored reaction enthalpy offers a promising route for tuning the thermodynamics of Mg-based hydrogen storage alloys.
