To find a method for estimating the surface area of ceria–zirconia in composite three-way catalysts, successive O2/H2/O2 chemisorption measurements were performed at room temperature on model Pd and/or Rh/Ce0.63Zr0.37O2 catalysts previously reduced

The importance of Pt and Pd in noble metal-barium oxide type NOx storage catalysts was investigated. Model Pt/BaO/Al2O3 and Pd/BaO/Al2O3 catalysts were prepared and evaluated with respect to NOx storage capacity, activity towards NO reduction under l

Measurements of the oxygen storage capacity (OSC) were performed on several aged PtRh/CeO2–Al2O3 industrial catalysts, using different techniques, i.e., TPR experiments, O2 and H2/O2 chemisorption. The obtained OSC values were compared to the catal

Successive O2/H2/O2 chemisorption measurements were performed at room temperature over Pt/CeO2 catalysts of different BET surface areas after reduction at 573 K under H2. It has been determined that about 4 μatom of oxygen per m2 of ceria is require

The influence of a chlorinated precursor on the redox properties of ceria was studied by comparing two Pt/CeO2–Al2O3 catalysts prepared from hexachloroplatinic acid and platinum acetylacetonate. In absence of chlorine, a dispersion value higher tha

Hydrogen chemisorption and temperature programmed reduction were used to study the modification of the redox properties of a PdRh/CeO 2 -ZrO 2 catalyst after ageing at 1323 and 1423 K. In presence of Pd or Rh, large quantities of hydrogen are adsorbe

The ceria surface area of a commercial Pt-Rh three-way catalyst was determined after laboratory hydrothermal aging at 1173-1373 K and after 200 h on engine bench. It was measured by X-ray diffraction (XRD) line broadening analysis and by a method bas
