Effect of iron on the hydriding properties of the Mg6Pd hydrogen storage system

The effects of iron addition on the hydriding properties of Mg6Pd were investigated. It was found that 15 min of co-milling Mg6Pd and Fe in a high energy mill was sufficient to improve the sorption kinetics. Rietveld refinement of neutron powder diffraction patterns indicated that the presence of iron drastically modifies the system's micro-structure. A possible link between structure and hydrogen storage properties is discussed.
