Efficient mineralization of dimethyl phthalate by catalytic ozonation using TiO2/Al2O3 catalyst

► The mineralization efficiency of DMP using TiO2/Al2O3 catalyst was the highest. ► The use of TiO2/Al2O3 catalyst would increase utilization efficiency of fed ozone. ► The activity of TiO2/Al2O3 catalyst can be mostly recovered by incineration.
