Abstract: In this paper the additive effect of potassium promoter on the Ni-Co-O and Zn-Co-O composite oxide catalysts was investigated by using XRD,TPR and XPS techniques, Theresults show that the specific area of these catalysts increases 4~5 times by the potassiumaddition and the catalytic activity of acetone and alcohol oxidation is enhanced.

Key words: potassium promoter, Ni-Co-O, Zn-Co-O, composite oxide
