| Abstract: | A ZrO2-MnO2 catalyst was prepared by the co-precipitation method,and modified with CeO2,MoO3,and WO3 by impregnation. The catalytic activity of the monolithic catalysts for selective catalytic reduction of NOx with NH3(NH3-SCR) was studied. All the catalysts were characterized by low temperature nitrogen adsorption-desorption,X-ray diffraction,X-ray photoelectron spectroscopy,and NH3/NO-temperature-programmed desorption. The results show that the phase of the catalysts is Mn0.2Zr0.8O1.8 solid solution,and C... |
