| 英文摘要 | The interface of nanojunctions plays an important role in the performance of heterogeneous catalysts. However, it is highly challenging to construct nanojunctions which are usually prepared by complex multi-step processes. Metal-organic frameworks (MOFs), with designable metal centers and tunable organic ligands, are promising precursors for the one-step synthesis of nanojunctions. Herein, we prepared porous CeO2/Co3O4 nanojunctions by direct annealing of MOFs in air. These unique nanojunctions exhibit remarkable catalytic activity for CO oxidation, which can achieve complete oxidization of CO to CO2 at 110 degrees C. In contrast, the temperature required for 100% CO oxidation is 190 degrees C for pure Co3O4. Moreover, the nanojunctions can maintain complete CO conversion after 16 h at 110 degrees C. Density functional theory calculations revealed that the enhancement in the catalytic activity of CeO2/Co3O4 nanojunctions can be attributed to the charge transfer through the interfaces of the nanojunctions. |
