Abstract

In this paper, we have studied the structure of nanometer composite oxides La_1-x· Sr_xFeO_3-δ by means of Mössbauer spectroscopy, IR, XRD, and TG, and pointed out that the catalytic activity for complete oxidation of methane was related to the Fe⁴⁺ content, its distribution and oxygen content. Catalytic activity increased with the increase of disordered Fe⁴⁺ content, and decreased with the appearance of ordered Fe⁴⁺. The oxygen content of nanometer oxide was higher than that of large particle oxide with the same content of doped Sr, this resulted in the increase of catalytic activity for nanometer oxide.
