MnEuOx-0.1 shows excellent SCR activity and broad operating temperature window. The SCR reactions over MnOx and MnEuOx-0.1 are mainly controlled by L-H mechanism (<150 °C). The SCR reactions over MnOx and MnEuOx-0.1 are mainly controlled by E-R mechanism (>150 °C). The enhanced NO oxidation and NH3 adsorption are the main reasons for the excellent SCR performance of MnEuOx-0.1.
