Structural transformation and redox chemistry of Pd/CeO 2 during SO2 -induced sulfurization: An in situ XAFS study

Key Points

• This research aims to understand how Pd/CeO2 catalysts change structurally and chemically when exposed to sulfur dioxide.
• Utilized in situ XAFS spectroscopy to analyze the catalysts during sulfurization.
• Performed linear combination fitting analysis on Ce L-edge data to assess structural changes.
• Documented significant structural evolution of Pd/CeO2 under SO2 exposure.
• Observed important changes in redox chemistry indicated by shifts in absorption spectra.
