Study on the catalytic reduction mechanism of SO2 by CO over doped copper perovskite catalyst in presence of oxygen

The reduction mechanism of SO2 by CO using LaCoO3 and doped copper as catalysts was investigated. The activity, selectivity of sulfur and the COS amount under various reaction conditions were tested. The results showed that the Cu doped catalysts were better than the undoped catalyst and 10% copper-doping gave the optimum catalyst.
