摘　　要：The selective catalytic reduction(SCR) of NOx using MnOx and CeO2 supported on viscose-based active carbon fibers(ACF) at 120 ℃～270 ℃ relatively lower than the temperature when using V2O5/TiO2-anatase catalyst was studied.As a result,CeO2/ACF shows a better catalysis than MNOx/ACF,which is not affected by the reaction temperature. NO conversion of 85% is reached with the 10%-CeO2/ACF catalyst at the whole temperature window.Furthermore,a series of MnOx-CeO2/ACF composite catalysts were studied.The results show that the loading method of catalyst affects its activity.The selective catalytic reduction （SCR） of NOx using MnOx and CeO2 supported on viscose-based active carbon fibers （ACF） at 120℃ -270℃ relatively lower than the temperature when using V2O5/TiO2-anatase catalyst was studied.
