Catalytic destruction of pentachlorobenzene in simulated flue gas by a V2O5-WO3/TiO2 catalyst

► Pentachlorobenzene in simulated flue gas can be destructed by a V2O5-WO3/TiO2 catalyst. ► The coexisting SO2 and NH3 have negative effect and NO has positive effect on PeCB conversion. ► PeCB molecules are destructed in three reaction pathways.
