Iron-Cobalt nanoparticles (Co/Fe molar ratio: 1/5) have been prepared by a simple co-precipitation method and employed as catalyst in low-temperature CO oxidation. The prepared catalysts were characterized by X-ray diffraction (XRD), N2 adsorption (BET), Transmition electron microscopy (TEM) techniques. The results showed that the calcination temperature has a significant effect on catalytic performance of prepared catalysts. Increasing in calcination temperature increased the crystallite and particle size and decreased the specific surface area which caused a decrease in catalytic activity of prepared catalysts.
