DeNOx activity over Mn/TiO2 catalyst: Effect of preparation method |
| 초록 |
Mn-based catalysts have been commonly regarded as eco-friendly low temperature SCR catalysts.However, a direct comparative study for the Mn-based catalyst with respect to the preparation methods has been rarely reported.In the present study, the catalytic activity and properties of s-Mn/TiO2 catalyst prepared by sol-gel method have been systematically compared to that of i-Mn/TiO2 catalyst prepared by impregnation method.The deNOx performance of the s-Mn/TiO2 catalyst is much superior to that of i-Mn/TiO2 in the whole reaction temperature region.Based upon the XRD and TEM-EDS study, Mn is basically incorporated into the matrix of Ti over s-Mn/TiO2 and then makes a solid solution with TiO2, whereas that simply exists on the surface of TiO2 over the i-Mn/TiO2 catalyst.The well dispersed Mn over s-Mn/TiO2 is the primary cause for the high deNOx performance compared to that over i-Mn/TiO2 catalyst. |
