中文摘要：

通过XRD、H2-TPR、NH3（NO）-TPD和N2吸附-脱附等分析测试手段,研究了Ni掺杂锰氧化物催化剂选择催化还原NO活性的影响。研究发现Ni0.3Mn0.7Ox催化剂的NH3选择催化还原NO的活性最好,其可能原因是掺杂Ni后Ni0.3Mn0.7Ox催化剂的氧化还原能力得到提高,比表面积和孔容增加及有利于低温NH3和NO的吸附。

英文摘要：

Ni doping manganese oxides catalysts were studied for selective catalytic reduction of NO by XRD, H2- TPR, NH3 （NO）-TPD and N2 adsorption-desorption. The study found that the catalyst Ni0.3 Mn0.7Ox showed the best selective catalytic reduction activity, the reasons may be as follows： Ni0.3 Mn0.7Ox catalyst showed improved redox, increased specific surface area and pore volume, at the same time, added NH3 and NO adsorption at low temperature.
