Abstract

CeO₂ -based catalysts are widely studied in 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, an interfacial reaction between metal-organic framework (MOF)-derived carbon and KMnO₄ to synthesize CeO₂ -MnO₂ , 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 CeO₂ crystallites under a high calcination temperature and, more importantly, intimate contact within CeO₂ /C is conveyed to CeO₂ /MnO₂ after the interfacial reaction; this is responsible for the high catalytic activity of CeO₂ -MnO₂ towards CO oxidation.
