摘要：

Amorphous FeTi1,2 was prepared from the powder mixture of elemental Fe and Ti by ball milling. The catalytic reaction ball milling method was adopted to prepare Mg-FeTi1,2 (amorphous) composite. The composite possesses rapid H-absorption rate, high H-capacity, low working temperature, as well as superior oxidation-resistance. During catalytic reaction ball milling and hydriding/dehydriding cycles, the phase stability of amorphous FeTi1,2 was examined. The favorable hydrogenation performance is mainly attributed to the combined effects of the catalytic efficiency of amorphous FeTi1,2 and the nanostructure of Mg. (C) 2002 Elsevier Science B.V.
