The structures of these catalysts were determined by XRD. The percentage of Mn 4+ ion in the catalysts was measured by chemical analysis. The activity of oxidation of CO over that series of catalysts was tested by pulsing process in differential reactor. The results of various measurements are discussed in this paper as well.展开更多
