Electrical and catalytic properties of cerium-tin mixed oxides in CO depollution reaction

- Co-precipitated SnO2-CeO2 catalysts are used for the CO oxidation.
- The surface behaviour was studied by electrical conductivity in operando conditions.
- The reaction mechanism can be assimilated to a Mars van Krevelan mechanism.
- Improved deep oxidation of CO has been found with co-precipitated SnO2-CeO2.
