This paper studied the activity and mechanisms of MnO_x-CeO₂-SnO₂ for low temperature NH₃-SCR reaction. Results showed that low temperature activities of MnO_x-CeO₂ were improved significantly by doping with Sn. Different nitrates formed on these catalysts and monodentate nitrates were more active. A L-H mechanism was proposed in this research.
