<p></p><p>In the present study, we have studied the effect of doping of noble metal ions in Ce-pyrochlores for dry reforming of methane (DRM). Two series of noble metal (Pt and Ru) doped pyrochlores i.e. Ce<sub>2</sub>Zr<sub>2</sub>O<sub>7</sub> and Ce<sub>2</sub>Ti<sub>2</sub>O<sub>7</sub> have been studied. Reducibility of the synthesized samples was measured to understand the interplay between the metal and support. A detailed material characterization was performed both pre-and post-reaction to highlight the changes on the surface of the catalyst. Further, the nature of surface intermediates was investigated by in situ FTIR studies. Based on these experimental insights, a comprehensive reaction pathway was developed and kinetic model was derived.</p><br><p></p>
