Mg is a promising light-weight material that has superior hydrogen storage capacity. However H2 storage in Mg typically requires high temperature, ∼500–600 K. Furthermore it has been shown that there is a peculiar film thickness effect on H2 sorption in Mg films, that is thinner Mg films desorb H2 a...
