Abstract: Construction of composite metal interfaces with synergistic catalysis is an important research field for CO preferential oxidation in H 2 steam (CO-PROX). Microwave electromagnetic loss can effectively compensate the thermal action on the active interface derived from metal-organic frameworks (MOFs). Herein, a trimetallic CuCoCe-MOF is derived to construct Cu–Co–Ce oxidation active interface oriented by magnetic, conduction and relaxation loss, which inhibit the high temperature deactivation due to sintering. Equipped with the tandem microwave pyrolysis, the intermediate CuCoCe/C fully exposes electromagnetic characteristic and heterogeneous interfaces. Subsequently, microwave strengthened CuCoCeO x exhibits an excellent CO-PROX activity window with the more than 85% CO conversion within 80–210 °C. Besides, in-situ Raman and in-situ DRIFTs investigations demonstrate that the equilibrium of active interfacial oxygen vacancy via hydrogen is crucial for the temperature window broadening of CO-PROX. This work provides a route for the efficient conversion of microwave electromagnetic energy to enhance the active interface for synergistic catalysis. Microwave electromagnetic loss regulation of Cu–Co–Ce oxidation active interface overcomes the transition dependence of intermetallic coupling on thermal action of traditional MOFs derivation for boosting the synergistic catalytic activity of CO-PROX. [Display omitted] • Microwave pyrolysis of MOFs fully exposes Cu–Co–Ce oxidation interface. • Electromagnetic loss facilitates the strengthening of CuCOCeO x active interface. • The optimum activity temperature of microwave pyrolysis is lower than normal. • Doping of magnetic Co exhibits a broadened CO preferential oxidation window. • In-situ Raman and DRIFTs reveal the role of hydrogen equilibrium oxygen vacancy.
