Conclusions
-
1.
The hydrides of Ce and Nd are catalytically active in the hydrogenation of ethylene; the activity of the hydrides depends on the conditions of preliminary thermovacuum treatment and the method of conducting the reaction.
-
2.
The catalytic activity of the hydrides of Ce and Nd is evidently associated with the presence of superstoichiometric hydrogen in the lattice of the inactive dihydrides.
