Abstract

Active carbon (AC)-supported dihydrides of europium and ytterbium were prepared by depositing finely divided metallic lanthanide on AC from liquid ammonia solutions of Eu and Yb metals, respectively, followed by hydriding under a hydrogen flow at 298-673 K. Upon heat treatment of YbH2/AC and EuH1.9/AC in vacuum, hydrogenation activity for olefins appeared.
