MnOx在ZrO2上分散状态及对CO氧化的影响
The Dispersed States of Manganese Species on Mn-O/ZrO2 Catalysts and its Influents on the Catalytic Performance
【Abstract】 Mn-O/ZrO2 catalysts were prepared by impregnation method and were characterizedby XRD, TPR and TPD-MS. The oxidation activity of CO on these catalysts was also studied.The restults indicated that the interaction between MnOx and ZrO2 would restrained the phasetransformation of ZrO2, and raised the dispersion of MnOx species on ZrO2. The highly-dispersedMnOx on ZrO2 is predominant contributors in catalytic activity of the Mn-O/ZrO2 catalysts.
