Promoting effect of CeO2 in a Cu/CeO2 catalyst: lowering of redox potentials of Cu species in the CeO2 matrix
Abstract
The promoting effect of CeO2 in a Cu/CeO2 catalyst for CO oxidation and NO reduction compared to CuO and Cu/ZrO2 is deduced to be based on lowering of redox potentials of copper species in the Cu/CeO2 matrix in relation to CuO and Cu/ZrO2.
