Summary:In this study, the activity and structural properties of catalysts prepared by mechanochemical method under dry condition were studied. A dry milling was used as a mechanochemical method. The precursors of vanadium were NH4VO3 and V2O5. The activity and characterization of the catalysts prepared by dry milling were compared with those prepared by impregnation. In addition, the correlation between the catalytic activity and the structural characteristics was observed through XRD, Raman, and H2-TPR analysis. As a result, the monomeric vanadate species exhibited excellent redox characteristics, which were confirmed to be related to the catalytic activity. KCI Citation Count: 0
