Abstract
In the presence of rhodium, the H-2-CeO2 interaction is to a large ext ent reversible, simple evacuation of the reduced sample has been demon strated to promote reoxidation of the support; this explains some puzz ling effects of the reduction/evacuation treatments on the actual oxid ation state of ceria in Rh-CeO2 catalysts.
