Complementary and Spatially Resolved Operando Spectroscopic Investigation of Pt/Al₂O₃ and Pt/CeO₂ Catalysts during CO/NO Conversion
The composition of reaction mixtures strongly influences the structural evolution and performance of noble metal-based catalysts. In this work, we compared the effect of the simultaneous presence of CO and NO on the noble metal state and CO oxidation activity of Pt/Al2O3 and Pt/CeO2 catalysts under close-to-stoichiometric conditions using complementary in situ/operando X-ray and infrared spectroscopic techniques.
