Abstract

Solid oxide cell (SOC) perovskite electrode materials (BSCF (Ba0.5Sr0.5Co0.8Fe0.2O3-δ), LSCF (La0.6Sr0.4Co0.2Fe0.8O3-δ) and LSCM (La0.75Sr0.25Cr0.5Mn0.5O3-δ)) were synthesised using microwave-assisted reverse-strike co-precipitation method and tested for soot oxidation activity. The calcined perovskite materials were characterized using FT-IR, XRD, SEM and BSE, BETand BJH and XPS analysis.The mean activation energy for so otoxidation was calculated from Ozawa plots at various heat ingrates(5,10,15 and20K/min)atdifferentlevelsofsootconversions(T10 toT90)forBSCF,LSCMandLSCFperovskitematerialsandwasaround 133 ± 11.5, 138 ± 9.9 and 152 ± 7.2 kJ/mol, respectively. Irrespective of the heating rates, BSCF material showed the lowest T50 temperature than compared to other samples, and it is correlated to the presence of Fe3O4 as a secondary phase
