X-ray absorption spectroscopy was performed at Diamond Light Source, UK, at B18 for the Pd/In2O3 & Pd/In2O3/Al2O3 species. Data was collected at the Pd and In K-edges in transmission mode using a QEXAFS setup with fast scanning Si(311) crystal monochromators. The time resolution here was roughly 90 seconds per spectrum. Samples were packed into an in-house custom-made capillary system designed and constructed by Diamond Light Source. 50 mg of 200-300 μm catalyst particles were packed between 3 cm of quartz wool.
