Metal-Organic Framework (MOF)-Derived Carbon-Mediated Interfacial Reaction for the Synthesis of CeO -MnO Catalysts.

CeO -based catalysts are widely studied in catalysis fields. Developing one novel synthetic approach to increase the intimate contact between CeO and secondary species is of particular importance for enhancing catalytic activities. Herein, an interfacial reaction between metal-organic framework (MOF)-derived carbon and KMnO to synthesize CeO -MnO , 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 crystallites under a high calcination temperature and, more importantly, intimate contact within CeO /C is conveyed to CeO /MnO after the interfacial reaction; this is responsible for the high catalytic activity of CeO -MnO towards CO oxidation.
