Ceria added Sb-V2O5/TiO2 catalysts for low temperature NH3 SCR: Physico-chemical properties and catalytic activity

- Addition of ceria enhanced NOx conversion and induced SO2 and water resistance.
- The ceria loading increased the Brønsted acidity was investigated by DRIFTS.
- Enhanced NOx conversion above 350 °C by retarding direct oxidation of NH3.
- Increase in total acidity, reducibility and surface oxygen species (Oα,Oβ) was observed.
