A 2.25 at.% V decorated Mg nanoblade array has been fabricated by a dynamic shadowing growth technique. It can absorb and desorb hydrogen rapidly at temperatures T>500 K after activation by one hydrogenation cycling, with low hydrogen absorption activation energy of 35.0 +/- 1.2 kJ/mol H2 and desorption activation energy of 65.0 +/- 0.3 kJ/mol H2. The saturated hydrogen content in Mg nanoblades decreases gradually with the number of cyclings, which is mainly caused by the formation and growth… CONTINUE READING
