THE EFFECT OF THE D-ELECTRON CONCENTRATION ON THE ABSORPTION CAPACITY OF SOME SYSTEMS FOR HYDROGEN STORAGE

The experimental data on the hydrogen absorption capacity of binary and pseudobinary intermetallic Laves phases, magnesium intermetallics, and mechanically alloyed mixtures of magnesium and 3-d metal oxides are subjected to analysis, on the basis of which it may be concluded that there is a qualitative correlation between the absorption capacity and the concentration of d-electrons in single-phase materials. For transition metals of the same period the absorption capacity is found to decrease with increasing d-electron concentration.
