Résumé:Title screen
The ambient temperature carbon monoxide oxidation is one of the important topics in the present scenario. In this paper, we prepared various types of catalysts from the precursors of cobalt nitrate, cerium nitrate, copper nitrate and manganese nitrate for the oxidation of CO. Among the prepared catalysts, the cerium nitrate precursor showed the best performance for CO oxidation at low temperature. The activity of the catalysts was measured in different calcination conditions like stagnant air, flowing air and reactive calcination (4.5% CO in air). The activity test was done in the reactor under the following reaction conditions: 100 mg of catalyst, 2.5% CO in the air and the reaction temperature was increased from ambient to a higher value at which complete oxidation of CO was achieved. The characterization of the catalyst was done by several techniques like XRD, FTIR, SEM-EDX, XPS and BET. The order of activity for different catalysts was as follows: Ce-Oxide > Mn-Oxide > Cu-Oxide > Co-Oxide.
