The promotional effect of precious metals in composite oxides has been observed in several catalytic reactions. In the present study, investigation of the CO oxidation with O-2 and NO-CO redox reaction over Pd-containing cobalt-manganese composite was discussed. The composite oxides were prepared via glycine-aided combustion method. The physical properties of the catalysts were studied using X-ray diffraction, BET surface area, SEM, TEM and XPS. The strength of surface oxygen and surface reactivity of metal and CO were studied by H-2-TPR and CO-pulse titration. It was observed that CO oxidation in cobalt-manganese composite oxide containing 5% PdO starts from 30 degrees C and the reaction gets completed at 65 degrees C. Also in NO-CO redox reaction, it shows complete detoxification at 170 degrees C with a good stability.
