Abstract
Official abstract text for this publication.
A method for preparing a magnesium-based hydrogen storage material, includes: a Mg—Ce—Ni family amorphous alloy is prepared by a rapid cooling process; the amorphous alloy is pulverized, so as to obtain a amorphous powder; the amorphous alloy is activated, so as to obtain a MgH 2 —Mg 2 NiH 4 —CeH 2.73 family nanocrystalline composite; the abovementioned composite is carried out a hydrogen absorption and desorption cycle, then the composite is placed in a pure Ar atmosphere for passivation, finally, the passivated composite is oxidized, so as to obtain a MgH 2 —Mg 2 NiH 4 —CeH 2.73 —CeO 2 family nanocrystalline composite.
First claim
Opening claim text (preview).
The invention claimed is: 1.
