Oxygen storage capacity of promoted Rh/CeC2 catalysts. Exceptional behavior of RhCu/CeO2
Résumé
The effect of various additives (V, Cr, Mn, Fe, Co, Ni, Cu and Pb) on the oxygen storage capacity (OSC) of CeO2 and Rh/CeO2 catalysts was investigated. Copper is an excellent promoter of OSC conferring to Rh a very high resistance to sintering (900°C, 2% O2).
