Abstract

Abstract:

Mn-O/ZrO2 catalysts were prepared by impregnation method and were characterized by XRD, TPR and TPD-MS. The oxidation activity of CO on these catalysts was also studied. The results indicated that the interaction between MnOx and ZrO2 would restrained the phase transformation of ZrO2, and raised the dispersion of MnOx species on ZrO2. The highly-dispersed MnOx on ZrO2 is predominant contributors in catalytic activity of the Mn-O/ZrO2 catalysts.

Key words: Manganese oxide, ZrO2, Dispersed state, Catalytic performance
