CeO2-based catalysts are widely studied in the catalysis fields. Developing one novel synthetic approach to increase the intimate contact between CeO2 and secondary species is of particular importance for enhancing catalytic activities. Herein, we design an interfacial reaction between MOF-derived Carbon and KMnO4 to synthesize CeO2-MnO2, where the Carbon is derived from the pyrolysis of Ce-MOFs under inert atmosphere. The MOF-derived Carbon is found to restrain the growth of CeO2 crystallites at high calcination temperature, and more importantly, the intimate contact within CeO2/C is conveyed to CeO2/MnO2 after interfacial reaction, which are responsible for high catalytic activity of CeO2-MnO2 towards CO oxidation. |
