Summary: This study reports real-time observations of the dehydrogenation of a Mg2FeH6-MgH2 composite using in situ transmission electron microscopy (TEM) with advanced spatial and temporal resolution. Through careful control and systematic variations of the reaction temperature and electron dose rate, the characteristic decomposition of Mg2FeH6 into Mg and Fe on the nanometer scale is visualized. The formation and growth of nanostructured Fe clusters in Mg metal during dehydrogenation are verified, and the desorption kinetics of the two coexisting phases are separately evaluated. These findings provide useful guidelines for designing hydrogen sorption conditions and improving solid-state hydrogen storage systems.

Summary: The hydrogen sorption performances of the 4MgH(2) + LiAlH4 system destabilized with 5 wt% Al2TiO5 showed significantly improved dehydrogenation temperature and kinetics. The introduction of Al2TiO5 resulted in earlier hydrogen liberation and enhanced absorption and desorption kinetics, indicating a synergistic effect on hydrogen storage behavior.

Summary: The presence of defects in blue phosphorene can lead to changes in its electronic structure and hydrogen storage capacity, with lower formation energies for vacancies and potential for enhanced hydrogen storage compared to other 2D materials. Metal decoration on defective blue phosphorene can increase hydrogen storage capacity, with stable structures at room temperature, making it a promising candidate for hydrogen storage applications. Comparing with defective black phosphorene, defective blue phosphorene shows higher hydrogen storage capacity.

Summary: Large-scale application of hydrogen requires safe, reliable and efficient storage technologies. Cryo-compressed hydrogen (CcH2) storage combines solid adsorption technology to reduce hydrogen storage pressure and improve density. Activated carbon and metal-organic framework materials (MOFs) are used as adsorbents. The combined storage achieves higher hydrogen density and lower pressure compared to pure adsorption or pure CcH2 storage.

Summary: Catalyst doping with MnMoO4 has been shown to significantly enhance the hydrogen storage performance of MgH2, reducing dehydrogenation temperature, increasing hydrogen storage capacity, and maintaining high performance after 20 cycles. The synergy between Mn and MgMo2O7 may play a key role in promoting hydrogen dissociation and diffusion, improving the overall hydrogen storage performance of MgH2.

Summary: Si@PVDF composite microspheres with Si nanopowder uniformly distributed were prepared by electrostatic spraying method. The improved interfacial contact quality in Si@PVDF led to enhanced chemical reactivity, as evidenced by reduced reaction onset temperature, peak temperature, and apparent activation energy compared to physically mixed Si/PVDF counterpart. Si/PVDF could not be ignited by Joule heating, while self-sustained combustion propagation was observed for Si@PVDF pellets. The combustion process of Si@PVDF pellets was influenced by equivalence ratio, pellet porosity, and O2 accessibility in the environment.

Summary: The iron nanopowder obtained by electrical explosion of wires, passivated by air, and stored for a long time (up to 18 years) under natural conditions was characterized using various analytical techniques. It was found that the iron nanopowder remained stable towards oxidation by air at ambient temperature, but exhibited high reactivity during heating. Atmospheric air humidity was considered an important factor influencing the activity of the iron nanopowder.

Summary: In this study, four different SrBr2/EVM composites were prepared and characterized for their micro and macro-structural features. The adsorption and desorption behaviors of the composites were tested, and it was found that the carrying capacity linearly increased with SrBr2 concentration, but excessive salt loading would lead to deliquescence and reduced adsorption performance at high humidity.

Summary: The addition of SrTiO3 significantly improves the hydrogen sorption performance of the 4MgH(2)-Li3AlH6 composite, mainly due to the alteration of its microstructure and pulverization effect. SrTiO3 demonstrates a good catalytic ability to the 4MgH(2)-Li3AlH6 system, reducing the onset decomposition temperature and enhancing rehydrogenation kinetics performance.
