Effect of doping with different amounts of nickel on the selective catalytic reduction NO of manganese oxides

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．
