“…Ren et al [ 110 ] found that TiMn 2 could effectively improve the hydrogen storage performance of MgH 2 , and no phase change was found in the catalyst during the experiments. Later, catalysts, such as Ti-Mn-Cr [ 111 ] and Ti-Cr-Mn-Fe-V [ 112 ], were found to produce finer particles after mechanical alloying and, therefore, had greater activity. In addition, the improved dehydrogenation performance of MgH 2 may be related to a more uniform distribution of alloying elements [ 111 , 112 ].…”

Due to its high hydrogen storage efficiency and safety, Mg/MgH2 stands out from many solid hydrogen storage materials and is considered as one of the most promising solid hydrogen storage materials. However, thermodynamic/kinetic deficiencies of the performance of Mg/MgH2 limit its practical applications for which a series of improvements have been carried out by scholars. This paper summarizes, analyzes and organizes the current research status of the hydrogen storage performance of Mg/MgH2 and its improvement measures, discusses in detail the hot studies on improving the hydrogen storage performance of Mg/MgH2 (improvement measures, such as alloying treatment, nano-treatment and catalyst doping), and focuses on the discussion and in-depth analysis of the catalytic effects and mechanisms of various metal-based catalysts on the kinetic and cyclic performance of Mg/MgH2. Finally, the challenges and opportunities faced by Mg/MgH2 are discussed, and strategies to improve its hydrogen storage performance are proposed to provide ideas and help for the next research in Mg/MgH2 and the whole field of hydrogen storage.

“…Dai et al 106 studied the stability and hydrogen absorption performance of TiMn 2 surface and Mg/TiMn 2 interface system using the first principle calculation method and found that inserting MgH 2 in to the TiMn 2 layer can greatly improve the hydrogen absorption performance of Mg, which will expand the practical application potential of Mg as a hydrogen storage medium. Khodaparast et al 107 prepared a composite consisting of MgH 2 + 5 at% Ti–Mn–Cr by mechanically milling MgH 2 powder and Ti–Mn–Cr based alloy powder synthesized by electric arc furnace melt spinning. The dehydrogenation temperature of MgH 2 was reduced from 399 °C to 345 °C.…”

“…The dehydrogenation temperature of TiVMn was within 217°C, and the dehydrogenation was completed at 270°C for only 2 min, showing good dehydrogenation performance. Khodaparast et al [43] prepared MgH 2 -5at %TiÀ MnÀ Cr composites with an average particle size of 800 nm by melt spinning. After introducing TiÀ MnÀ Cr into MgH 2 and mechanical alloying for 15 h, the dehydrogenation temperature decreased to 345°C, which was lower than that of MgH 2 powder under the same conditions.…”

Magnesium hydride (MgH 2 ) has become a very promising hydrogen storage material because of its high hydrogen storage capacity, good reversibility and low cost. However, high thermodynamic stability and slow kinetic performance of MgH 2 limit its practical application. In the past few decades, many alternative methods have been designed to solve this problem. A large number of studies have demonstrated that the use of metal catalyst doping modification, MgH 2 nanocrystallization and other methods can greatly improve the hydrogen absorption and dehydrogenation performance of MgH 2 . Therefore, this paper reviews and summarizes the modification effect of transition metal catalyst doping on the hydrogen storage performance of MgH 2 , especially the catalysis on the de/rehydrogenation performance of MgH 2 . In addition, promoting effects of carbon materials, transition metal alloys and compounds on the hydrogen storage performance of MgH 2 were also summarized. Finally, the existing problems and challenges of MgH 2 as hydrogen storage materials are discussed, and some possible strategies are proposed.
