Investigating the differences of active oxygen species and carbonate species on the surface of Ce0.95M (M = Mn and Zr)0.05O2−δ catalysts prepared by the aerosol method during CO oxidation using operando TPR-DRIFTS-MS

, and its existence is the decisive step of CO oxidation. The above results provide a new way to regulate the surface oxygen species and carbonate species of Ce based catalysts in the later stages.
