Desorption reaction in MgH2 studied with in situ μ+SR

Author affiliations

Abstract

In order to study the mechanism determining the desorption temperature (Td) of hydrogen storage materials, we have measured positive muon spin rotation and relaxation (μ+SR) in MgH2 over a wide temperature range including its Td. The pressure in the sample cell due to desorbed H2 was measured in parallel with the μ+SR measurements under static conditions. Such in situ μ+SR measurements revealed that hydrogen starts to diffuse in MgH2 well below Td. This indicates the important role of hydrogen diffusion in accelerating the desorption reaction by removing the reaction product, i.e. H2, from the reaction system.
