| 英文摘要 | The active species in supported metal catalysts are elusive to identify, and large quantities of inert species can cause significant waste. Herein, using a stoichiometrically precise synthetic method, we prepare atomically dispersed palladium-cerium oxide (Pd-1/CeO2) and hexapalladium cluster-cerium oxide (Pd-6/CeO2), as confirmed by spherical-aberration-corrected transmission electron microscopy and X-ray absorption fine structure spectroscopy. For aerobic alcohol oxidation, Pd-1/CeO2 shows extremely high catalytic activity with a TOF of 6739 h(-1) and satisfactory selectivity (almost 100% for benzaldehyde), while Pd-6/CeO2 is inactive, indicating that the true active species are single Pd atoms. Theoretical simulations reveal that the bulkier Pd-6 clusters hinder the interactions between hydroxy groups and the CeO2 surface, thus suppressing synergy of Pd-Ce perimeter. |
