Abstract

In this study, the Cu-doped Ce‒Mn/ATP denitration catalyst was prepared by impregnation method and heterogeneous precipitation method and its denitrification performance was tested. It was found that the denitrification effect was obviously improved after Cu doping. And the denitration effect of the catalyst prepared by the heterogeneous precipitation method was better and the denitrification rate was above 98%. Under this method, n(Cu: Mn) = 1 had the best denitration effect, with a maximum of 99.76%. The prepared catalysts were characterized by means of XRD, XPS, BET, and SEM. The results showed that CuMn2O4 and CuO appeared in the Cu doped catalysts. Moreover, the doping of Cu enriched the pore structure and surface morphology of the catalyst, so that the catalyst showed good denitrification performance.
