摘要: A series of Sn-substituted strontium ferrates SrFe1−xSnxO3−δ (x = 0, 0.25, 0.50, 0.75 and 1.0) were prepared by the polymerized complex method. The influence substitution Fe in SrFeO3−δ with Sn on structural, redox, catalytic properties was investigated. X-ray diffraction 57Fe Mossbauer analyses revealed that partial expanded lattice perovskite-type structure, leading to elongation Fe–O bonds. resulted decline particle size increase specific surface area. H2-TPR TG measurements a H2 or O2 flow indicated significantly accelerated redox rates at 500 °C. Due increased area enhanced properties, partially substituted showed higher activity than for combustion benzene.
