“…Because of its environmentally friendly nature, abundant resources, and high energy density, hydrogen has been considered as a predominant energy carrier for the sustainable development of human society. − However, the applications of hydrogen energy are severely restricted due mainly to the lack of safe and efficient hydrogen storage methods. , Storing hydrogen in solid-state materials shows great advantages over high-pressure gaseous and low-temperature liquid storage in terms of safety and efficiency. , Among the solid-state hydrogen storage materials, magnesium-based hydrides have attracted extensive attention because of their high theoretical gravimetric (7.6 wt %, MgH 2 ) and volumetric hydrogen capacities, good reversibility, low cost, nontoxicity, and high safety. − Unfortunately, the high thermodynamic stability (Δ H f ≈ −76 kJ mol –1 H 2 ) and sluggish de/hydrogenation kinetics of MgH 2 significantly restrict its practical applications. − …”

MXenes are considered as potential support materials for nanoconfinement of MgH2/Mg to improve the hydrogen storage properties. However, it has never been realized so far due to the stacking and oxidation problems caused by unexpected surface terminations (−OH, −O, etc.) on MXenes. In this study, hexadecyl trimethylammonium bromide was used to build a 3D Ti3C2T x architecture of folded nanosheets to reduce the stacking risk of flakes, and a bottom-up self-assembly strategy was successfully applied to synthesize ultradispersed MgH2 nanoparticles anchored on the surface of the annealed 3D Ti3C2T x (Ti-MX). The composite with a 60 wt % loading of MgH2 NPs, 60MgH2@Ti-MX, starts to decompose at 140 °C and is capable of releasing 3.0 wt % H2 at 150 °C within 2.5 h. In addition, a reversible capacity up to 4.0 wt % H2 was still maintained after 60 cycles at 200 °C without obvious loss in kinetics. In situ high-resolution TEM observations of the decomposition process together with other analyses revealed that the nanosize effect caused by the nanoconfinement and the multiphasic interfaces between MgH2(Mg) and Ti-MX, especially the in situ formed catalytic TiH2, were main reasons accounting for the superior hydrogen sorption performances.

“…32 For the XRD patterns of the α/β-NiMoO 4 @NF electrode, the diffraction peaks at 26.55°, 27.22°, 33.89°, and 37.10° marked by red circle can be indexed to the (002), (11−2), (22−2) and (400) facets of β-NiMoO 4 (JCPDS No. 45-0142), 33 and the other peaks can be well-assigned to α-NiMoO 4 . Thus, the XRD results conclusively demonstrate that the prepared NiMoO 4 electrode contains α and β phases, which are in line with the HRTEM results (Fig.…”

Hydrogen storage technology is related to the process of hydrogen energy market. Efficient and safe hydrogen storage materials have always been the goal pursued by people. In the past few years, oceans of materials for hydrogen storage have been researched, MgH2 is considered to be one of the most potential hydrogen storage materials due to its high hydrogen storage capacity, good reversibility and price advantage. However, its development has been limited by its good thermodynamic stability and slow dehydrogenation kinetics. In this paper, the improvement of hydrogen storage performance of MgH2 is summarized from catalyst doping, MgH2 nanosizing, alloying and the construction of composite system. In particular, catalyst doping and MgH2 nanosizing will be more effective modification strategies. With the development of nanotechnology, monatomic catalyst will also become a research hotspot. In view of the changes in thermodynamic properties caused by the nanofabrication of MgH2, the loadless freestanding nano MgH2 will undoubtedly receive more attention.
