摘要:
The invention concerns solid compositions, consisting entirely or partly of a mixed oxide of formula (I): TZraMbOx, obtainable by heat treatment of a mixture of hydroxides of elements T (rare-earth(s)), Zr and M (metal element(s)). The invention also concerns the use of said compositions, in particular for hydrogen storage. In that context, the invention also concerns mixed oxohydride compositions of formula (I): TZraMbOx'Hy and their use as hydrogen reservoir.
