| 제목 | A study on the low temperature SCR activity enhancement with the addition of tungsten of Mn-Ce-Ti catalyst |
| 초록 | This study is performed on the reaction characteristics of the selective catalytic reduction (SCR) using ammonia for a removal of nitrogen oxides (NOx). Mn-Ce-W-Ti catalysts were prepared by a wet impregnation method. Tungsten loadings of catalysts were 0-10 wt.%. The SCR activity is increased to the maximum when it included 5 wt.% tungsten. But it showed a tendency to decrease when tungsten added more than that. The properties of the catalyst were evaluated using H2 temperature-programmed reduction (H2-TPR) and X-ray photoelectron spectroscopy (XPS). As a result, the Mn4+ and Ce3+ peaks increased with the addition of W in H2-TPR. Also, when the tungsten 5 wt.%, the ratio of Mn4+ and Ce3+ species present the highest. Thus, The ratio of Mn4+ and Ce3+ was comfimed an important factor on the reaction of low temperature SCR.
