Abstract

Operando X-ray absorption fine structure (XAFS) investigations were performed on Pt/γ-Al2O3 during the total oxidation of C3H6 in reducing and oxidizing atmospheres. Study of the Pt valance state and catalytic conversion behavior as a function of temperature revealed that both the creation of metallic Pt sites and the activation of adsorbed species on Pt are important for the functioning of the catalytic reaction at low temperature.
