In this work, cobalt-silver composite oxide catalysts were synthesized by coprecipitation from an aqueous solution of cobalt and silver nitrate. The effects of silver loading (5, 10, 20 %) and calcination temperature were (573, 673, 773 K) investigated. The BET surface area, XRD and deactivation curves were used to characterize the catalysts. This study found that the 10 % Ag/Co{sub 3}O{sub 4} calcined at 523 K was the most active for CO oxidation. Therefore, the kinetics of carbon monoxide oxidation on this catalyst in the presence of synthetic gas mixture in the temperature range of 363-398 K were determined using a differential flow reactor. The order of reaction with respect to CO and O{sub 2} concentrations and the activation energy were found to be 0.2, 1 and 22 kcal.mol respectively. 1 ref., 3 figs., 1 tab.
