Abstract

The Ce_0.5Zr_0.3Al_0.2O_1.9/Pd- γ-Al₂O₃ catalyst prepared by a mechanochemical route and calcined at 1000 °C for 20 h in air atmosphere to evaluate the thermal stability. The prepared Ce_0.5Zr_0.3Al_0.2O _1.9/Pd-γ-Al₂O₃ catalyst was characterized for the oxygen storage capacity (OSC) and CO oxidation activity in automotive catalysis. For the characterization, X-ray diffraction, transmission electron microscopy and the Brunauer-Emmet-Teller (BET) technique were employed. The OSC values of all samples were measured at 600 °C using thermogravimetric- differential thermal analysis. Ce_0.5Zr_0.3Al _0.2O_1.9/Pd-γ-Al₂O₃ catalyst calcined at 1000 °C for 20 h with a BET surface area of 41 m² g^-1 exhibited the considerably high OSC of 583 μmol-O g ^-1 and good OSC performance stability. The same synthesis route was employed for the preparation of the CeO₂/Pd-γ-Al ₂O₃ and Ce_0.5Zr_0.5O ₂/Pd-γ-Al₂O₃ for comparison.
