Selective oxidation of alcohols with molecular oxygen catalyzed by Ru/MnOx/CeO2 under mild conditions

A manganese oxides supported on cerium(IV) oxide MnOx/CeO2 precatalyst by wetness impregnation with manganese(II) acetate and cerium(IV) oxide. A Ru/MnOx/CeO2 catalyst was prepared by wetness impregnation of MnOx/CeO2 precatalyst with aqueous solution of ruthenium(III) chloride. The Ru/MnOx/CeO2 catalyst has high catalytic activities for the oxidation of alcohols to the corresponding carbonyl compounds. Especially, the advantage of the present catalyst is the smooth oxidation of alcohols at 300 K under molecular oxygen atmosphere.
