The effects of Fe, Mg, and Pt-doping on the improvement of Ni stabilized on Al₂O₃-CeO₃ catalysts for methane dry reforming.

ABSTRACT: Herein, the promotional effects of Mg, Fe, and Pt on Ni-based catalysts supported on Al₂O₃-CeO₂ (Ni/Al₂O₃-CeO₂) were investigated in the dry reforming of methane (DRM) reaction. The interaction of a suitable amount of MgO and FeO with Ce₂O₃ stabilized in the catalysts was demonstrated by the temperature-programmed desorption of CO₂ (CO₂-TPD). Ce₂O₃ has a high basicity for adsorbing CO₂, generating a monoclinic Ce₂O₂CO₃ species in the DRM reaction. Surface oxygen ions were also produced by adding MgO and FeO, as demonstrated by the temperature-programmed reduction of H₂ (H₂-TPR). Monoclinic Ce
