Abstract

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 (Ea) in H2–D2 equilibration provided a strong experimental proof for the d-band theory. The energy of Cd was lowered by the formation of intermetallics, making Ni–H(D) bonding weaker and the Ea lower.
