Abstract

Starting from a synchronous combination of EXAFS with Diffuse reflectance infrared spectroscopy (DRIFTS), a novel combination of very hard (86 keV) X-ray diffraction with DRIFTS will be outlined. The potential for combining these techniques for the in situ study of the dynamic structural-reactive behaviour of working catalysts with high (≪1 second) time resolution will be demonstrated using the examples of nanoparticulate Pd/Al2O3 and Pd/CeZrO4/Al2O3 catalysts during CO/NO cycling. Lastly, recent results, obtained from 1 wt% Pt/Al2O3 catalysts during stoichiometric - lean CO/O2 cycling, using a time resolved Pair distribution function (PDF) approach to analysis of hard (60 keV) X-ray scattering data will be presented and discussed.
