Abstract :
Among methods of changing variables influencing catalyst activity, mechanochemical treatments is known to change catalyst characteristics. Characterization of catalyst was carried out by XRD, Raman, H2-TPR and XPS. The catalyst increased monomeric species is changed redox characteristic. Accordingly, the mechanochemical method can lower temperature for reoxidation by oxygen, and thus it is believed to inhibit the decline of SCR reaction activity at low temperature.
