چکیده:

In this paper, low temperature CO oxidation over Cobalt-Magnesium mixed oxide nanocatalysts with different ratio was investigated. The nanocatalysts were prepared with a facile co-precipitation method. The prepared samples were characterized by X-ray diffraction (XRD) and BET surface area method (BET). The catalytic results show that the addition of Co to magnesium oxide has a good effect on increasing CO conversion at lower temperatures. In addition our results show that pretreating of catalyst under oxidative atmosphere displays the highest activity and very good repeatability even in reaction atmosphere with CO presence that is a destroyer catalyst agent
