Surface characterization of (La_(1-x)Sr_x)MnO_3 synthesized using a sol-gel process and solid-state reaction

摘要

Recently, there has been an interest in examining the oxidation of hydrocarbons on perovskite-type oxides [1-5]. (La1-xSrx)MnO3, (La1-xSrx)FeO3, and (La1-xSrx)CoO3 show high oxidation activity for carbon monoxide, and (Lao.6Sro 4)MnO3 is almost as active as Pt/Al2O3 [1]. To improve the catalysis, it is necessary to synthesize perovskite-type oxides with a large specific surface area.
