Kinetics of catalytic oxidation of CO over copper-manganese oxide catalyst

The hopcalite-like catalyst was prepared by co-precipitation, which showed excellent activity and stability for CO oxidation at room-temperature. The activity of carbon monoxide oxidation was investigated at different temperature. The kinetics of carbon monoxide oxidation over copper-manganese oxides catalysts was obtained by means of recycling batch reactor. As a result, CO oxidation followed different reaction mechanism at a broad range of the experimental temperature. The reaction activation energy of CO oxidation was found to be 64.08 kJ mol−1 for 273–313 K and 12.15 kJ mol−1 for 333–373 K, respectively.
