Summary: Hydrogen energy is considered important for low carbon energy and has wide application prospects. The production of hydrogen plays a crucial role in the hydrogen industry chain. The safe and stable acquisition of hydrogen remains a pressing issue, particularly for temporary or portable usage scenarios, due to inadequate infrastructure. This paper systematically investigates the research progress of hydrolytic hydrogen production materials in the past 15 years, categorizing them into four systems based on hydrolysis characteristics. The advantages, disadvantages, and technical bottlenecks of different materials are thoroughly analyzed, and promising candidates are identified for industrialization feasibility and cost-effectiveness.

Summary: It was unexpectedly found that the desorption behavior of magnesium rich Mg-Ni hydrides improved after exposure to air for a certain period. After 4 months of exposure, the dehydrogenation peak and onset temperature were lowered by 150°C and 130°C, respectively. Furthermore, the air-exposed sample exhibited rapid hydrogen absorption and desorption rates at 300°C. The improvement in reactivity is attributed to the refining of the powders, the in-situ formed magnesium hydroxide layer, and the presence of Ni as active catalytic sites.

Summary: With the urgent need to find green, low-cost, and high-efficiency energy resources due to the depletion of fossil fuels and global warming, hydrogen has been considered as a potential alternative. However, effective and safe hydrogen storage techniques are now becoming a bottleneck for the hydrogen economy. Magnesium-based hydrogen storage materials have garnered interest due to their high storage capacity, low cost, and excellent reversibility. Nano-structuring has proven to be an effective strategy to enhance the thermodynamic and kinetic properties of these materials.

Summary: A novel unconventional coprecipitation procedure combined with a simple and fast microwave-assisted hydrothermal treatment was used to synthesize a new nanocrystalline magnetic cobalt ferrite with photo-Fenton activity. The study demonstrated that microwave hydrothermal treatment is essential for obtaining magnetic and photoactive Co-ferrite, with photoactivity mainly attributed to the migration of Co2+ ions during the MAH treatment.

Summary: This study investigated the addition of a non-hydride forming element in the multicomponent Ti-V-Nb-M system using the CALPHAD approach. Cr was selected as the fourth alloying element, and (TiVNb)(100-x)Cr-x alloys were synthesized and found to absorb hydrogen at room temperature without activation treatment. Increasing the Cr content in the alloys resulted in higher equilibrium pressures, indicating tunable hydrogen storage properties could be achieved.

Summary: FeCoNiCrMoB alloys produced by melt-spinning exhibit excellent corrosion resistance in chloride media, with the formation of a nanometric-thick film composed of Fe, Co, Ni, Cr, and Mo on the alloys' surface responsible for granting the corrosion resistance of all alloys. Excessive crystallization forming borides may compromise the corrosion resistance of the alloys, highlighting the importance of maintaining amorphous structures in enhancing corrosion resistance.

Summary: Fe76.5Nb8.5B15 (at.%) ultrafine eutectic (UE) coatings were processed by laser cladding, resulting in the formation of nanoscale borides that improved mechanical properties. The wear performance of the coatings and substrate was evaluated, showing different wear mechanisms such as abrasive, adhesive, shearing, and delamination. Oxide particles responsible for tribofilm formation and debris nanoparticles from fracture or breakage were observed. Overall, the Fe-Nb-B ultrafine eutectics laser clad coatings exhibited comparable or superior wear resistance properties to commercial alloys and other materials processed by rapid solidification.
