Abstract

Electrolytic manganese anode mud is a promising low temperature SCR catalyst. In this study, the effect of Pb and K ion in EMAM on the low temperature SCR was investigated via experimental and DFT method. Pb modification can improve the surface unsaturation so that the oxidation ability of MnO₂ is improved. Therefore, ammonia is easily oxidated on the surface of Pb-MnO₂. K ion can moderate the surface of MnO₂ and lower the energy barrier of dehydrogenation for low temperature SCR process. However, Pb can inhibit N₂O formation thereby improving the N₂ selectivity.
