Abstract
The Ag-loaded perovskite-type oxide catalysts (Ag/LaFeO3-CN and Ag/LaFeO3-imp) were prepared using two different methods, and their catalytic activities for carbon combustion were examined. Ag loading was observed to exhibit a positive effect on the catalytic activity of carbon combustion for an Ag/LaFeO3-CN catalyst that was prepared by the calcination of an Ag-loaded heteronuclear metal cyano-complex precursor. However, Ag loading was not observed to be significantly effective in case of Ag/LaFeO3-imp that was prepared by a general impregnation method. Such a noticeable enhancement in the activity of an Ag/LaFeO3-CN catalyst was assumed to originate from both the high dispersion of Ag that was loaded on LaFeO3 and from the formation of reactive oxygen species between metallic Ag species and the perovskite-type oxide.
