摘要：

In the presence of rhodium, the H-2-CeO2 interaction is to a large extent reversible, simple evacuation of the reduced sample has been demonstrated to promote reoxidation of the support; this explains some puzzling effects of the reduction/evacuation treatments on the actual oxidation state of ceria in Rh-CeO2 catalysts.
