Oxygen Storage Capacity of Promoted Rh/CeO2 Catalysts - Exceptional Behavior of Rhcu/CeO2
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-degrees-C, 2% O2).
