AbstractThe design and preparation of suitable supports are of great importance for gold catalysts to attain excellent catalytic performance for alcohol oxidation. In this work, we found that ZnO-CuO mixed oxides supported gold catalysts showed much better catalytic activity for base-free aerobic oxidation of benzyl alcohol than Au/ZnO and Au/CuO catalysts, and among them Au/Zn0.7Cu0.3O displayed the best catalytic performance. In addition, the Au/Zn0.7Cu0.3O catalyst could selectively catalyze the aerobic oxidation of a wide range of alcohols to produce the corresponding carbonyl compounds with high yields under mild conditions without base. Further characterizations indicated that the outstanding catalytic performance of Au/Zn0.7Cu0.3O was correlated with the small size of Au nanoparticles (NPs), good low-temperature reducibility, high concentration of surface oxygen species, and collaborative interaction between Au NPs and mixed oxide.
