摘要：

The well-characterized La-Co oxide overlayer was prepared on the surface of ZrO2 powder by impregnating ZrO2 with aqueous solutions of the mixtures of La and Co acetates followed by calcination at various temperatures. The preparation processes and the structure of La-Co oxide overlayers were investigated in detail by IR, XRD, XPS, EDX, TEM, and adsorption of NO and pyridine. It was concluded that a highly dispersed La-Co oxide overlayer which may have the LaCoO3 perovskite structure was formed. The resulting La-Co/ZrO2 catalysts showed very high catalytic activities for complete oxidation of propane.
