Summary: In this study, K2NiF6 was used as an additive to improve the dehydrogenation properties of LiAlH4. The addition of K2NiF6 significantly reduced the decomposition temperature and enhanced the dehydrogenation kinetics of LiAlH4. The morphology study showed that the LiAlH4 particles became smaller and less agglomerated when K2NiF6 was added. The in situ formation of new phases during the dehydrogenation process, as well as a reduction in particle size, were believed to contribute to the improved dehydrogenation characteristics of LiAlH4.

Summary: Magnesium hydride (MgH2) is considered as a safe and efficient hydrogen storage material due to its high hydrogen content and reversibility. By introducing nanosized cobalt titanate (CoTiO3) into the MgH2 system, it was found that the composite with 10% CoTiO3 doping exhibited the most outstanding performance, significantly reducing the decomposition temperature of MgH2 and demonstrating rapid hydrogen absorption and desorption rates at low temperatures. The enhanced performance is believed to be attributed to the in situ formation of specific compounds during the heating process, which greatly impact the behavior of MgH2.

Summary: Metal hydrides such as MgH2 and NaBH4 have high potential for solid-state hydrogen storage. However, a dehydrogenation process is required prior to hydrogen utilization. The hydrolysis method is a possible way to extract or generate hydrogen, but issues like passivation layer, high cost and sluggish self-hydrolysis can be overcome with the help of catalysts. Studies have shown that adding catalysts like chloride, oxide, fluoride, platinum, ruthenium, cobalt, and nickel can significantly enhance the amount of hydrogen released during the hydrolysis of MgH2 and NaBH4.
