Enhancement of hydrogen sorption properties of MgH2 with a MgF2 catalyst
Abstract Effect of a MgF 2 catalyst, prepared by ball-milling, on the hydrogen desorption
ability of commercial MgH 2 was investigated. When MgH 2 was catalyzed with a MgF 2
composite, it exhibited good cyclability and sharp faceting, with a small grain size (around
10 nm), which differs from those of pure MgH 2. The addition of the MgF 2 catalyst suggests
that the F anion could significantly contribute to the cyclability of Mg particles and aid in the
inhibition of MgH 2 grain growth.
