SnO2–MnOx–CeO2 catalysts prepared by a co-precipitation method have been investigated for NH3-SCR reaction. The catalyst with a molar ratio of Sn / (Sn + Mn + Ce) = 0.1 showed complete conversion of NO in a temperature range of 80–230 °C. A remarkably high activity, N2 selectivity and SO2 resistance was obtained at 200–500 °C, attributed to the significantly enhanced Lewis acid sites that are created by surface sulfation during SO2-containing SCR reaction.
