Homogeneous precipitation of Ceria based transition metal catalysts for low temperature NH3-SCR of NOx |
| 초록 |
The Ceria based transition metal oxide catalysts for NOx reduction with NH3 were synthesized by homogeneous precipitation by urea. All the catalysts showed high BET-surface area and better dispersion of transition metal oxide species. Surface acidity and reducibility of the prepared catalysts are crucial for a NOx reduction at wide temperatures (low to high). The catalysts were characterized by XRD, BET-surface area, NH3-TPD, H2-TPR, SEM and XPS. NOx conversion was evaluated at different temperatures in the presence of 3 vol% O2, H2O and SO2. |
