| 英文摘要 | Atomically precise bimetallic MxAu25-x(SR)(18) (M=Cu and Ag, R= CH2CH2Ph) nanoclusters are investigated as oxide-supported catalysts for the catalytic oxidation of styrene. Their catalytic properties are compared with the case of homogold Au-25(SR)(18) nanocluster. The oxide-supported MxAu25-x(SR)(18) catalysts give rise to 42-82% conversion of styrene at 70 degrees C using (diacetoxyiodo)benzene (PhI(OAc)2) as the oxidant. The Ag and Cu dopants are found to modulate both the activity (i.e., conversion of styrene) and the selectivity to styrene epoxide or benzaldehyde (major products). The AgxAu25-x(SR)(18) clusters exhibit higher activity and benzaldehyde selectivity than the homogold cluster, while the CuxAu25-x(SR)(18) clusters primarily enhance the selectivity to benzaldehyde without significantly changing the activity. The results provide insights into the factors that influence the catalytic activity and selectivity in styrene oxidation. (C) 2015 Elsevier B.V. All rights reserved. |
