In this study, a novel perovskite-based three-way catalyst (LaFe0.57Co0.37Pd0.06O3/Ce0.8Zr0.2O2/Al2O3) with high performance, thermal stability and SO2 poisoning resistance was developed. The performance of the developed catalyst was compared to a standard catalyst based on dispersed metal (Pd/Rh/ Ce0.8Zr0.2O2 / Al2O3). Performance evaluations were carried out in a dynamic activity test system that simulates redox fluctuations in the exhaust of gasoline engines. ICP-OES, BET surface area, X-ray diffraction, TEM-EDX spectroscopy, DRIFTS and CO chemisorption techniques were used for the characterization of catalysts. The performances of the catalysts before aging were obtained close to each other. After hydrothermal aging at 1273 K, perovskit...
