A synthesis route based on the occurrence of redox reactions between MnVII, MnII and CeIII precursors leads to nanostructured MnCeOx systems with high surface area (120-250 m 2/g) and a quasi-atomic dispersion of the active phase. Larger accessibility and higher oxidation state enhance the redox activity of the surface active Mn sites resulting in an improved mobility and availability of surface oxygen that greatly promotes the CO oxidation activity of the MnCeO x system at low temperature (20-150°C).

Abstract

A synthesis route based on the occurrence of redox reactions between MnVII, MnII and CeIII precursors leads to nanostructured MnCeOx systems with high surface area (120-250 m 2/g) and a quasi-atomic dispersion of the active phase. Larger accessibility and higher oxidation state enhance the redox activity of the surface active Mn sites resulting in an improved mobility and availability of surface oxygen that greatly promotes the CO oxidation activity of the MnCeO x system at low temperature (20-150°C).
