Metal–Organic Framework (MOF)‐Derived Carbon‐Mediated Interfacial Reaction for the Synthesis of CeO2−MnO2 Catalysts

Abstract CeO 2 ‐based catalysts are widely studied in catalysis fields. Developing one novel synthetic approach to increase the intimate contact between CeO 2 and secondary species is of particular importance for enhancing catalytic activities. Herein, an interfacial reaction between metal–organic framework (MOF)‐derived carbon and KMnO 4 to synthesize CeO 2 −MnO 2 , in which carbon is derived from the pyrolysis of Ce‐MOFs under an inert atmosphere, is described. The MOF‐derived carbon is found to restrain the growth of CeO 2 crystallites under a high calcination temperature and, more importantly, intimate contact within CeO 2 /C is conveyed to CeO 2 /MnO 2 after the interfacial reaction; this is responsible for the high catalytic activity of CeO 2 −MnO 2 towards CO oxidation.
