Abstract

Strontium-substituted LaCoO3 and double-substituted La0.9Sr0.1CoO3 by Cu, Fe and Ni perovskite catalysts were prepared via citric acid sol–gel method. The precursors were calcined at 750 °C in stagnant air. The precursor of the catalyst showing the best activity for soot oxidation was also reactively calcined in a flowing reactive mixture of 4.6 % CO in air at 750 °C. The catalysts were characterized by N2-sorption, XRD, FTIR and SEM. The substitution of Sr in LaCoO3 enhanced the activity of the catalyst. Further, increase in the activities of the catalysts was observed for double substitution of Cu, Ni and Fe in La0.9Sr0.1CoO3. The catalyst formulation La0.9Sr0.1Co0.5Fe0.5O3, calcined in air (Cat-5A) and reactively calcined (Cat-5B), showed higher activities than other four optimized catalysts composition calcined in air. Cat-5B exhibited the best activity resulting in total soot combustion at the lowest temperature of 325 °C. The best performance of Cat-5B was associated with its partially reduced perovskite phase as a result of reactive calcination leading to lattice vacancies and defects. Cat-5B has good thermal stability found in a repeated cycles of soot combustion experiments.
