Abstract

Conventional DeNO_X strategies (SCR and SNCR) suffer from a series of problems, such as high operating temperature and NH₃ escape. In this study, Fe₂(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 °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 Fe₂(MoO₄)₃ showed excellent stability and superior water resistance.
