Abstract

In the current study, a series of cobalt doped SmFeO3 perovskites (SmFe1-yCoyO3, y=0.1 to 0.35) were synthesized via EDTA-citrate method and used for soot removal applications. All the fabricated catalysts were characterized using XRD, SEM, BET surface area analysis and XPS analysis. It was found that the doping of Co into SmFeO3 perovskites considerable influences on morphology and soot oxidation reactions. The phase of the samples was investigated using XRD technique and examined the formation of orthorhombic phase till 30 mole% of Co-doped samples. All the samples exhibited low BET surface areas which are in the range of 2-6 m2/gm. From SEM analysis, the samples showed surface morphological changes with spherical shaped crystals. Sm existed in +3 oxidation states; Fe as +3 and Co as +3 in all the samples as evidenced from XPS results. Soot oxidation activity tests, investigated using TGA instrument and showed that SmFe0.7Co0.3O3-δ exhibited better catalytic performance (T50%-496oC) when compared to un-doped SmFeO3 (T50%-560oC).
