摘要：

The introduction of transition metals in Mn/TiO2 catalysts played significant roles in oxidative abstraction of hydrogen from adsorbed ammonia during the selective catalytic reduction (SCR). Thermodynamic calculation studies showed that the SCR performance was in accordance with the ammonia oxidation with transition metals, and the reaction tendency for the ammonia oxidation was decreased in the following order: CuO > Co3O4 > NiO > Fe2O3 > Cr2O3 > ZnO > La2O3 > CeO2 > ZrO2. In addition, Mn/TiO2 catalyst doped metal (Fe and Cu) oxides enhanced performance for NOx conversion, being approximately 100% at 453 K. (C) 2014 Elsevier B.V. All rights reserved.
