Catalytic Activity of Multi-metallic Perovskite-Type Oxide Prepared by the Thermal Decomposition of Heteronuclear Cyano Complex, Sm[Fe x Co1?x (CN)6] · nH2O

摘要

The perovskite-type SmFe x Co1?x O3 oxides were prepared by the thermal decomposition of heteronuclear cyano complexes, Sm[Fe x Co1?x (CN)6] ? nH2O. XRD studies demonstrated that SmFe x Co1?x O3 catalyst prepared by the thermal decomposition of heteronuclear cyano complex at 1,273 K showed orthorhombic structure in whole range of x. The catalytic activity for CO oxidation was dependent on x in SmFe x Co1?x O3; the maximum activity was obtained for SmFe0.5Co0.5O3.
