Abstract

Hexagonal YbFeO3 (h-YbFeO3) were prepared by solvothermal and Pechini methods. Although the morphology of h-YbFeO3 synthesized by solvothermal method was hexagonal plate, h-YbFeO3 synthesized by the Pechini method was composed of large aggregates of irregularly-shaped fine particles. Activities of Ru catalysts supported on h-YbFeO3 for combustion reaction of propane or propene were investigated. For the support of the Ru catalyst, h-YbFeO3 synthesized by the solvothermal method was superior to that prepared by the Pechini method. Effects of the reaction temperatures of the solvothermal synthesis upon the activities of the Ru catalysts supported on the products were examined and it was found that the catalyst supported on crystallized h-YbFeO3 showed higher activity than the catalyst supported on an amorphous product having a large surface area.
