The high temperature reduction at 773 K of Rh-CeO2 catalysts induced a transient Rh-CeO2 interaction which enhances the rate of CO and CO2 hydrogenation; however, the activity dropped rapidly as a result of formation of water, which reoxidised CeO2 - x, restoring the normal behaviour.

Abstract
The high temperature reduction at 773 K of Rh-CeO2 catalysts induced a transient Rh-CeO2 interaction which enhances the rate of CO and CO2 hydrogenation; however, the activity dropped rapidly as a result of formation of water, which reoxidised CeO2 - x, restoring the normal behaviour.File in questo prodotto:
