Combustion‐type hydrogenation of nanostructured Mg‐based composites for hydrogen storage

摘要: In this study Reactive Ball Milling in hydrogen gas was used to synthesize nanostructured hydrogenated composites of Mg and V-based alloy. After desorption, the nanocomposites exhibited a dramatic facilitation rate H absorption by reduction temperature onset hydrogenation. These favourable changes were caused synergy catalytic effect alloy on heat release exothermic When initial interaction exceeded threshold, rather low, value 20–125°C, depending H2 pressure, composition sample its total amount, combustion-type hydrogenation took place. With optimal parameters applied, completed just 5–70 s accompanied significant release. The observed features can be utilized reach fast recharge Mg-based stores develop efficient management systems.
