Enhanced hydrogen storage performances of binary Mg-Y nanoscale particles

Infrared spectroscopic study of solvation and size effects on reactions between water molecules and neutral rare-earth metals

“…Such reduced reactivity of hydrogen atoms might contribute to reducing the activation energy of the dehydrogenation reaction of the hydrogen storage materials. 4–6 These three types of hydrogen atoms were also observed in the process of ethylene/acetylene hydrogenation catalyzed by CeO 2 , 14 and the reactivity sequence was consistent with our results. The deactivation of the CeO 2 catalyst has been rationalized by the overproduction with the formation of strongly bound M–OH groups that are difficult to remove from the surface.…”

“…[1][2][3] For instance, Ni@CeO 2 -doped MgH 2 hydrogen storage material reduces the dehydrogenation activation energy by 20.3 kcal mol −1 , which signicantly improves the hydrogen release property of MgH 2 material. [4][5][6] Rare-earth single-atom catalysts (SAC) are extensively exploited in the photocatalytic/electrocatalytic processes of O 2 /CO 2 /N 2 , etc. [7][8][9][10][11][12] Theoretical studies have veried that in the electrocatalytic reduction of O 2 , the rare-earth SAC undergoes the transformation from the poly-hydroxyl structure to the solvated water structure.…”
