In this study, the various structure Mn-Cr mixed oxide catalysts are synthesized by co-precipitation method and they are used as active catalysts for NH3 selective catalytic reduction. The Mn-Cr mixed oxide catalysts are characterized by X-ray diffraction, NH3-temperature programed desorption, H2-temperature programed reduction, X-ray photoelectron spectroscopy and Fourier-transform infrared spectroscopy. The prepared Mn-Cr layered structure mixed oxide catalyst was explored as a catalyst for NH3 selective catalytic reduction, resulted in an outstanding deNOx performance at low temperature. Moreover, the improved H2O and SO2 tolerance of Mn-Cr layered structure catalysts was also obtained. The enhanced NOx removal efficiency suggests that Mn based layered structure catalysts could be used as the effective catalyst for low temperature NH3-SCR processes. |
