Abstract

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. Ce2Zr2O7 and Ce2Ti2O7 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.
