Abstract: | A series of Sn-substituted strontium ferrates SrFe1-xSnxO3-delta (x = 0, 0.25, 0.50, 0.75 and 1.0) were prepared by the polymerized complex method. The influence of the substitution of Fe in SrFeO3-delta with Sn on structural, redox, and catalytic properties was investigated. X-ray diffraction and Fe-57 Mossbauer analyses revealed that the partial substitution of Fe with Sn expanded the lattice of the perovskite-type structure, leading to elongation of Fe-O bonds. The partial substitution resulted in the decline of the particle size and the increase of the specific surface area. H-2-TPR and TG measurements in a H-2 or O-2 flow indicated that the partial substitution significantly accelerated the redox rates of Fe at 500 degrees C. Due to the increased surface area and enhanced redox properties, the partially substituted SrFe1-xSnxO3-delta showed higher catalytic activity than SrFeO3-delta for the combustion of benzene. |
