Abstract: Four kinds of active carbon were used to reduce NO as both supports and reducing agents. The cupric oxide and ferric oxide supported on the active carbon greatly enhanced the conversion of NO reduction.The conversion depended on the reducibility of active carbon and metallic ions impregnated.Cupric oxide exhibited better promotion than ferric oxide.The active carbon with greater reducing ability tends to produce a higher conversion of NO reduction. Additionally,the dispersion of cupric oxide on active carbon is also a factor influencing NO reduction.
