In this report, the reaction characteristics of O2-NO-H2, H2O2, HCHO, CH4 systems were investigated, expecting the oxidation of NO to NO2. Main results were summerized as follows.
1) These chemicals (H2, H2O2, HCHO, CH4) have the effect of oxidizing NO to NO2 at 400-800°C in the presence of O2 (only H2O2 don't need the presence of O2)
2) In the case of H2O2 and HCHO, oxidation of NO to NO2 was occured at [M] / [NO] _??_ ([M] / [NO] molar ratio of added chemicals to NO), but in the case of H2 and CH4 higher value of [M] / [NO] was needed.
3) The important role of HO2 radicals in oxidation of NO to NO2 was recognized, from the kinetic model calculation including 22 species and 70 elementary reactions.
