Abstract: |
Magnesium-based hydrogen-storage materials were prepared by reactive ball-milling under hydrogen atmosphere with molybdenum as catalyst and coal-based carbon as dispersant. The microstructure, crystalline phase structure and hydrogen-storage properties were analyzed using TEM, XRD, DSC, etc. The results showed that the crystal structure of the materials was enhanced by adding molybdenum. MgH2 was crystalline body for hydrogen storage in the materials, and the crystalline structure of molybdenum in the materials didn’t change before and after dehydrogenation. It was also found that the dehydrogenation temperature of the material with molybdenum additive decreased, and the hydrogen-storage capacity and dehydrogenation rate increased, compared to the material without molybdenum additive.
