Controlling Multiple Active Sites on Pd-CeO2 for Sequential C-C Cross-coupling and Alcohol Oxidation in One Reaction System |
| 초록 |
Ceria-supported metal catalysts have been widely utilized for various single-step chemical transformations, but has rarely been used for a multistep organic reaction in one reaction system. Here, we investigate multiple active sites on Pd-CeO2 catalysts and optimize them for a multistep reaction of C-C cross-coupling and alcohol oxidation. Atomic-level studies reveal that metallic Pd0 and Pd-CeO2 interface are active sites on for C-C cross-coupling and oxidation, respectively. These active sites are controlled under the structural evolution of Pd-CeO2 during reductive heat-treatments. Accordingly, optimally reduced, Pd-CeO2 catalysts with both sites in balance are found to be ideal. Our strategy to design supported metal catalysts leads to one-pot sequential synthetic protocols for valuable building blocks. |
