Fund Project: This work was supported by the National Natural Science Foundation of China (21673142), National Engineering Laboratory for Mobile Source Emission Control Technology (NELMS2017A05), PetroChina Innovation Foundation (2018D-5007-0505), and Science Foundation of China University of Petroleum, Beijing (242017QNXZ02, 2462018BJC005).

Three-dimensional ordered macroporous (3DOM) La_1-xK_xNiO₃ perovskite-type catalysts were successfully prepared by a colloidal crystal template method and characterized by scanning electron microscopy, transmission electron microscopy, high-resolution transmission electron microscopy, energy-dispersive X-ray scattering elemental mapping, X-ray diffraction, Raman and X-ray photoelectron spectroscopy, and temperature-programmed reduction of H₂. Further, their catalytic activity in soot combustion was determined by temperature-programmed oxidation reaction. K substitution into the LaNiO₃ lattice led to remarkably improved catalytic activity of this catalyst in soot combustion. Amongst various catalysts, La_0.95K_0.05NiO₃ exhibited the highest activity in soot combustion (with its T₅₀ and S_CO₂ values being 338℃ and 98.2%, respectively), which is comparable to the catalytic activities of Pt-based catalysts under the condition of poor contact between the soot and the catalyst. K-substitution improves the valence state of Ni and increases the number of oxygen vacancies, thereby leading to increased density of surface-active oxygen species. The active oxygen species play a vital role in catalyzing the elimination of soot. The perovskite-type La_1-xK_xNiO₃ nanocatalysts with 3DOM structure without noble metals have potential for practical applications in the catalytic combustion of diesel soot particles.
