Abstract: Ceria-supported Cu, Ir, and Pd catalysts showed quite promising activity for transfer dehydrogenation of cyclohexanol and 2-octanol to cyclohexanone and 2-octanone, respectively, using styrene as the hydrogen acceptor. The Cu/CeO2 and Pd/CeO2 catalysts were more active than the previously reported Cu and Pd catalysts supported on Al2O3, and Ir/CeO2 exhibited extremely high activity. The reactivity of alcohols decreased in the order 2-octanol>cyclohexanol>benzyl alcohol>1-octanol. The synergetic effect between the metals and CeO2 as well as the effective coupling of dehydrogenation of alcohols and hydrogenation of styrene was responsible for the high catalytic activity.
