<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>
