Low temperature catalytic ozonation of toluene in flue gas over Mn-based catalysts: Effect of support property and SO2/water vapor addition

•Toluene catalytic ozonation in flue gas was evaluated under related industrial conditions.•The acidity and oxygen species on catalyst surface was related to catalytic activity.•The effect of SO2 and water vapor in flue gas on toluene oxidation were firstly investigated.•Toluene conversion efficiency could recover as SO2 and water vapor was stopped.
