Abstract

Metastable hexagonal YbFeO_3 (h-YbFeO_3) can be synthesized by the solvothermal reaction of ytterbium acetate and iron acetylacetonate in 1, 4-butanediol, although the stable phase for this composition is the orthorhombic phase. In a previous work, we found that h-YbFeO_3 catalysts show higher activities for combustion reaction than orthorhombic YbFeO_3. In this work, h-YbFeO_3 doped with various amounts of Mn were prepared by the solvothemal and polymerized complex methods and the activities for combustion of C_3H_8 were examined. Of the catalysts examined in this work, h-YbFe_<0.5>Mn_<0.5>O_3 prepared by the solvothermal method showed the highest activity.
