Time-resolved X-ray powder diffraction on a three-way catalyst at the GILDA beamline

CO oxidation with a Pt/ceria-zirconia catalyst has been studied by in situ X-ray diffraction at the beamline GILDA of ESRF. The time-resolved X-ray diffraction pattern of the catalyst was recorded by the translating imaging plate implemented at GILDA, while the CO₂ yield was monitored by a mass quadrupole spectrometer.
