N2O formation in the selective catalytic reduction of NOx with NH3 on a CeMoOx catalyst

- N2O is formed above 300 °C over the CeMoOx catalysts.
- The low molar MoOx content in CeOx (5% and 10%) inhibits N2O formation.
- High MoOx content enhances the N2O formation.
- The presence of H2O significantly suppresses the N2O formation.
