The calcined perovskite materials were characterized using FT-IR, XRD, SEM and BSE, BET and BJH and XPS analysis. The mean activation energy for soot oxidation was calculated from Ozawa plots at various heating rates (5, 10, 15 and 20 K/min) at different levels of soot conversions (T<inf>10</inf> to T<inf>90</inf>) for BSCF, LSCM and LSCF perovskite materials and was around 133 ± 11.5, 138 ± 9.9 and 152 ± 7.2 kJ/mol, respectively. Irrespective of the heating rates, BSCF material showed the lowest T<inf>50</inf> temperature than compared to other samples, and it is correlated to the presence of Fe<inf>3</inf>O<inf>4</inf> as a secondary phase. © 2019, Springer Nature Switzerland AG.Activation energyBarium compoundsChromium compoundsDustElectrodesHeating rateIron oxidesLanthanum compoundsMagnetiteManganese compoundsOxidationPerovskitePrecipitation (chemical)Solid oxide fuel cells (SOFC)SootElectrode materialLa0.6sr0.4co0.2fe0.8o3Microwave assistedOzawa plotsReverse-strike co-precipitation methodSecondary phaseSolid-oxide cellsSoot oxidationStrontium compounds
