| Abstract: | A novel V2O5/VOSO4 catalysts were screened and its performance of the catalytic decomposition of o dichlorobenzene（o-DCB） as a model of dioxin was investigated.The results indicated that the catalytic activity of V2O5/VOSO4 catalysts was enhanced with the increase of V2O5 content,which showed that V2O5 was the active component; the active component was dispersed well and the activity of supported V2O5/VOSO4 TiO2BaSO4 catalyst was improved obviously due to the decrease of the particle sizes of the catalyst.The catalytic removal rate of o dichlorobenzene over V2O5/VOSO4TiO2BaSO4 catalyst prepared under the optimizing process condition reached 97% at high space velocity. |
