Facilitating the dry reforming of methane with interfacial synergistic catalysis in an Ir@CeO2−x catalyst

Abstract The dry reforming of methane provides an attractive route to convert greenhouse gases (CH 4 and CO 2 ) into valuable syngas, so as to resolve the carbon cycle and environmental issues. However, the development of high-performance catalysts remains a huge challenge. Herein, we report a 0.6% Ir/CeO 2− x catalyst with a metal-support interface structure which exhibits high CH 4 (~72%) and CO 2 (~82%) conversion and a CH 4 reaction rate of ~973 μmol CH4 g cat −1 s −1 which is stable over 100 h at 700 °C. The performance of the catalyst is close to the state-of-the-art in this area of research. A combination of in situ spectroscopic characterization and theoretical calculations highlight the importance of…
