Conventional DeNO(X) strategies (SCR and SNCR) suffer from a series of problems, such as high operating temperature and NH3 escape. In this study, Fe-2(MoO4)(3) was first being applied in activating H2O2 vapor toward the oxidation of NO and impact factors, including H2O2 concentration, reaction temperature, GHSV, pH value, H2O2 solution feeding rate, and coexisting gases, were investigated. The results revealed that 92.1% NO conversion efficiency was achieved at 260 degrees C with a low H2O2/NO molar ratio of 4:1. The possible mechanism for the reaction pathways of NO was also discussed. Moreover, in comparison to most reported Fenton-like catalysts used for the elimination of NO, the prepared Fe-2(MoO4)(3) showed excellent stability and superior water resistance.
