Comparison Study on Support Effect of Co-Series Compound Oxide Catalysts Supported Rare Earth

The catalysts were prepared by the impregnation method and characterized thought X-ray powder diffraction (XRD), H2-temperature-programmed reduction (H2-TPR), measurement of surface area, differial thermal and thermogravimetric analysis. Rare-earth compound oxides La 0.8Sr0.2CoO3 act as active component; Alumina act as carriers. The effects were investigated on loading amounts of active components, calcinations temperature and the addition components on the catalytic oxidation of xylene.
