Investigations on the crystal plane effect of ceria on gold catalysis in the oxidative dehydrogenation of alcohols and amines in the liquid phase.

Gold nanoparticles supported on ceria{110} crystal planes were more reactive than on ceria{111} and {100} in the oxidative dehydrogenation of alcohols. Kinetic analysis and a Hammett plot suggest that hydride transfer is involved, and the cationic gold is catalytically active.
