“…Several studies have reported the successful preparation of magnesium-based hydrogen storage materials using the organic ligand-assisted method. For example, Grignard reagents provide a simple pathway for the thermal decomposition of Mg and/or MgH 2 [ 73 ]. For instance, di-tert-butyl magnesium decomposes to form MgH 2 /Mg at a low temperature of 167 °C, which is 100 °C lower than the temperature required for di-n-butyl magnesium to be converted to MgH 2 .…”

Additionally, the formation of metastable gamma-MgH 2 enables the MgH 2 synthesized from di-tert-butyl magnesium precursor to release hydrogen at 100 °C [ 73 ]. Aguey-Zinsou et al [ 74 ] synthesized MgH 2 nanoparticles with a core-shell structure using an organic ligand-assisted method.…”

Magnesium-based hydrogen storage materials have garnered significant attention due to their high hydrogen storage capacity, abundance, and low cost. However, the slow kinetics and high desorption temperature of magnesium hydride hinder its practical application. Various preparation methods have been developed to improve the hydrogen storage properties of magnesium-based materials. This review comprehensively summarizes the recent advances in the preparation methods of magnesium-based hydrogen storage materials, including mechanical ball milling, methanol-wrapped chemical vapor deposition, plasma-assisted ball milling, organic ligand-assisted synthesis, and other emerging methods. The principles, processes, key parameters, and modification strategies of each method are discussed in detail, along with representative research cases. Furthermore, the advantages and disadvantages of different preparation methods are compared and evaluated, and their influence on hydrogen storage properties is analyzed. The practical application potential of these methods is also assessed, considering factors such as hydrogen storage performance, scalability, and cost-effectiveness. Finally, the existing challenges and future research directions in this field are outlined, emphasizing the need for further development of high-performance and cost-effective magnesium-based hydrogen storage materials for clean energy applications. This review provides valuable insights and references for researchers working on the development of advanced magnesium-based hydrogen storage technologies.

“…Moreover, this method can be easily scaled up for large-scale production of magnesium-based hydrogen storage materials. Various solvents, such as water, ethanol, and polyols, can be used in solvothermal synthesis, depending on the desired properties of the final product [ 71 ]. The addition of surfactants or capping agents can further control the morphology and prevent the agglomeration of the nanoparticles [ 72 ].…”

Magnesium-based hydrogen storage alloys have attracted significant attention as promising materials for solid-state hydrogen storage due to their high hydrogen storage capacity, abundant reserves, low cost, and reversibility. However, the widespread application of these alloys is hindered by several challenges, including slow hydrogen absorption/desorption kinetics, high thermodynamic stability of magnesium hydride, and limited cycle life. This comprehensive review provides an in-depth overview of the recent advances in magnesium-based hydrogen storage alloys, covering their fundamental properties, synthesis methods, modification strategies, hydrogen storage performance, and potential applications. The review discusses the thermodynamic and kinetic properties of magnesium-based alloys, as well as the effects of alloying, nanostructuring, and surface modification on their hydrogen storage performance. The hydrogen absorption/desorption properties of different magnesium-based alloy systems are compared, and the influence of various modification strategies on these properties is examined. The review also explores the potential applications of magnesium-based hydrogen storage alloys, including mobile and stationary hydrogen storage, rechargeable batteries, and thermal energy storage. Finally, the current challenges and future research directions in this field are discussed, highlighting the need for fundamental understanding of hydrogen storage mechanisms, development of novel alloy compositions, optimization of modification strategies, integration of magnesium-based alloys into hydrogen storage systems, and collaboration between academia and industry.

“…Aguey-Zinsou's group prepared nanosized MgH 2 via a simple thermolysis path of Grignard reagent (di- tert -butylmagnesium, t -bu 2 Mg). 218 With the use of t -bu 2 Mg, large hexagonal structures of approximately 150 nm were formed, accompanied by smaller nanoparticles of around 5 nm that decorated the edges and surfaces of the large hexagonal structures. The synthesized MgH 2 released hydrogen starting from a temperature as low as 373 K. The Liu group further successfully synthesized 4–5 nm non-confined ultrafine MgH 2 NPs, which achieved 6.7 wt% reversible hydrogen storage.…”
