In this study, molecular insights into NO-promoted SO2 oxidation on model TiO2 with well-defined (001), (010), and (101) facets are investigated in the laboratory. The adsorbed SO2 is significantly promoted to transform into sulfate by the coexisting NO on the three facets. The appearance of active oxygen species indicates an active oxygen species-initiated NO oxidation. The resulting NO2 acts as an oxidant to convert adsorbed sulfite on hydroxyls to sulfate species. The (101) facet presents the best performance in the NO-promoted sulfate forma...
