Abstract: The catalytic performance of LaFe1−xNixO3 perovskites prepared by the Pechini method was studied in the high-temperature decomposition reaction of nitrous oxide at temperatures of 750–900 °C. The samples were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), transmission electron microscopy (TEM), adsorption (Sbet) and hydrogen thermo-programmed reduction (H2-TPR) methods. The prepared single-phase solids with specific surface areas of 4.7–8.4 m2 g−1 are porous particles (aggregates) of 10–100 μm composed of microblock crystallites. The surface of all samples is enriched with lanthanum. Increasing the Ni content increases the normalized per m2 catalytic activity of LaFe1−xNixO3 perovskites, their reducibility in hydrogen, the ratio of Fe + Ni/La and the content of low bond oxygen forms on the sample surface. The correlation of activity and low bond oxygen forms was revealed, which is consistent with the mechanism of reaction of nitrous oxide decomposition. For future industrial applications the LaFe0.4Ni0.6O3 perovskite is proposed due to its higher stability in the reaction medium as compared with samples with x > 0.6.
