摘要

In this study, a clear-cut relationship obtained between the d band centre (Cd) of Ni and Ni3M (M = Ge, Nb, Sn, Ta, Ti) intermetallics and their activation energy (E_a) in H2-D2 equilibration provided a strong experimental proof for the d-band theory. The energy of Ca was lowered by the formation of intermetallics, making Ni-H(D) bonding weaker and the E_a lower.
