The carbon monoxide is a toxic and life-threatening gas to humans and other forms of air-breathing life. In present time, the low-temperature oxidation of carbon monoxide is applicable in large scale of application in automobile and other fields. In this paper, the different types of cobalt precursors were prepared in the laboratory for oxidation of carbon monoxide at low temperature. The precursor was converted into the catalyst by calcination at 300oC temperature. The cobalt precursor first drying at 120oC temperature for 12h then calcined at 300oC in different calcination conditions. The catalytic activity measurements were examined in room temperature to 250oC, the 100mg of catalyst was used in presence of 2.5%CO with air and total flow rate was 60mL/min. They are several techniques has used for the characterization of the catalysts such as XRD, SEM-EDX, FTIR and XPS analysis. The low-temperature CO oxidation activity measurement showed in all of the catalyst and the best activity was obtained from cobalt oxalate precursor prepared catalyst at 110oC temperature. The order of activity for different cobalt precursor was as follows: Cobalt Oxalate > Cobalt Acetate > Cobalt Nitrate.
