Aiming at the influence of different solvent environments on Fe-MnOx catalysts during the preparation process,Fe-MnOx catalysts were prepared by a one-step co-precipitation method.The inf-luence of different solvent environments on catalyst activity during the synthesis of the catalyst was investigated.It was found that the catalyst prepared by glycerol as a solvent environment had the best low-temperature activity and sulfur resistance.Through a series of characterization analyses,it was found that the catalyst prepared in a glycerol environment has regular particle morphology and particle size,the largest specific surface area,abundant and evenly distributed pore structure,and the highest contents of Mn4+,Fe3+and Oα.Therefore,under the condition of 50℃and GHSV=30000/h,the catalyst can be used to improve the quality of the catalyst.It shows more than 80%NOx removal rate and better sulfur resistance.
