摘要

•Highly removal efficiency of NOx was achieved in TiO2/O3/H2O2 system.•Ti-OOH generated on TiO2 surface and react with O3 to form OH and O2−.•NOx removal was influenced by the amount of H2O2, reaction temperature and the concentration of SO2.•A reaction mechanism was established to interpret the NOx removal process.
