제목 Effect of Mn, Fe to cerium vanadate catalyst for NOx reduction with NH3
초록 The effect of Mn- and Fe- to cerium vanadate supported on TiO2-WO3-SiO2 catalyst were prepared and applied to SCR reaction. The properties of these catalysts were characterized by BET surface area, temperature programmed desorption/ reduction, X-ray diffraction methods. The preparation methods were compared. The catalysts showed high activity at high temperatures by ball-mill method. Cerium vanadate catalyst with Fe loaded exhibited higher NOx conversion than Mn loaded one at broad temperature range (250-500 oC). The effect of aging condition was also investigated. The redox and acid/base properties of catalyst played important roles on the performance of catalyst.
