Abstract
Mg-Ni composite hydrogen storage materials have been prepared by high energ y ball milling Mg and Ni powders and annealing in hydrogen atmosphere formi ng Mg2Ni catalytic phase. Mg65Ni35 (wt%) alloy can desorb 3.4 wt% H-2 at 29 0 degrees C and 4.8 wt% H-2 at 305 degrees C in 40 min. The improved desorp tion properties are attributed to the homogeneous distribution of nanocryst alline Mig and Mg2Ni phases. The structure and storage properties are not c hanged through 150 cycles of absorbtion at 300 degrees C and desorption at 305 degrees C. (C) 1999 Elsevier Science S.A. All rights reserved.
