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 Ni_0.4 Mn_0.6O_x showed the best SCR activity，the reasons may be as follows: Ni_0.4Mn_0.6O_x 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．
