Research Abstract |
Hydrogen-induced modification of the electronic structures in 4d and 3d transition metal hydrides was investigated using x-ray absorption spectroscopy. Relationship between hydrogenation property and the electronic structure of the TM hydrides was discussed. The element and orbital selectivity of XAS was used to probe the electronic structure. The characteristic XAS profiles near the absorption edgeindicated significant shifts in the Fermi energy due to hydrogenation, which differed depending on the elements. It was concluded that the difference of the electronic structure is strongly associated with the hydrogenation property.
