Abstract

Dehydrogenation in MgH2 was found to lead to a transition from an incubation stage controlled by nucleation to an accelerated stage controlled by the movement of the interface. Addition of carbon nanotubes destabilized Mg–H bonding and reduced the energy barrier for nucleation, which is mainly related to the electron affinity of their curved surface.
