Study on Sulfur Dioxide Decomposition over Oxygen

The oxygen-deficient ferrite (Fe 3 O 4-??) was prepared by reduction of the natural magnetite powder with CO, and the performance of the Fe 3 O 4-?? in decomposing SO 2 into elemental sulfur was investigated. The samples, prepared by wet ball-milling of the magnetite using water as solvent for 500 hours, were characterized by means of SEM and XRD, and their activity of decomposing SO 2 was
