Ammonia selective catalytic reduction of NO over Fe/Cu-SSZ-13
|
||
| A series of CHA-type Fex-Cu-SSZ-13 catalysts were prepared by liquid ion exchange method based on the one-pot synthesized Cu-SSZ-13 catalyst. The catalysts were applied to the selective catalytic reduction of NO with NH3 and were characterized by means of XRD, N2 adsorption/desorption, UV-Vis-DRS, H2-TPR, XPS and In situ DRIFTS. Fex-Cu-SSZ-13 catalysts achieved high NH3-SCR activity, excellent N2 selectivity from 150oC to 550oC, high hydrothermal stability and were highly resistant to high space velocity. The results may be attributed to the synergistic effects between copper and iron species. The results of H2-TPR, UV-Vis DRS and XPS indicated that more active sites and stronger redox capacity contributed to the excellent NH3-SCR performance upon the addition of Fe species into Cu-SSZ-13. In situ DRIFTS results showed that NO+ and NO3- generated from NO+O2 adsorption were the key intermediates and were further reduced to N2 by NH3. |
