Effects on the H2-sorption properties of Mg of Co (with various sizes) and CoO addition by reactive grinding

We tried to improve the H2-sorption properties of Mg by mechanical grinding under H2 (reactive grinding) with Co (with various particle sizes) and with CoO. The CoO addition has the best effect and the addition of smaller particles of Co (0.5–1.5 μm) has a better effect on the H2-sorption properties of Mg than the addition of larger particles of Co..
