Preparation and methane combustion catalytic activity of nanometer perovskite-type complex oxides La_(1-x)Sr_xFeO_3 and LaFe_(1-y)Mn_yO_3

摘要

Perovskite-type complex oxides (ABO_3) 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 properties.
