Abstract


Nickel-manganese oxides were studied for selective catalytic reduction of NO by XRD，H2-TPR and N2 adsorption-desorption. The study was found that the catalyst Ni0.4 Mn0.6Ox showed the best SCR activity，the reasons may be as follows: Ni0.4Mn0.6Ox catalyst showed the optimal synergistic effect between nickel and manganese and appropriate redox ability, which were conducive to NH3 under the condition of low temperature catalytic reduction of NO．

Keywords
