We follow the structural evolution of industrial catalysts, Pt and PtRe deposited on alumina, during the in situ sulfuration steps of the activation procedure using EXAFS spectroscopy. For the monometallic, we measure a large amount of sulfur (3S/Pt), as well as a decrease in platinum bonds (4.5 to
