摘要：
Lanthanum and barium ferrites as well as lanthanum cobaltate binary oxidic species supported on alumina and zirconia were tested for their catalytic activity for the CO oxidation reaction. Synthesized perovskite oxides were supported on alumina or zirconia by dry impregnation. For the same percent loading of the perovskite (5.8per cent), LaCoO3 /ZrO2 were found to be most active in comparison of La-Co-O solids supported on zirconia may be attributed to better reactivity of Co at B-site in comparison to Fe, homogeneous and higher dispersion on zirconia in comparison to alumina, ionic oxygen carrying capacity of zirconia and larger ionic size of Zr4+ ion.
