摘要
Perovskite-type complex oxides (ABO<sub>3</sub>) have a well-defined structure and high thermostability, and the oxidation state of metal ions as well as oxygen vacancies can be changed through partial substitution of metal ions at A or B site, so they are suitable model compounds for the study of the relationship between the solid state chemistry and the catalytic propertiest. LaFeO<sub>3</sub> and its partially cation-substituted oxide system prepared by solid-state reaction have been applied to the complete oxidation of methane,
