FeBeta||Mn–Ce/FeBeta catalyst was prepared by coating cordierite monolith with FeBeta zeolite followed by an impregnation of its downstream part by Mn–Ce solution. The resulting dual-zone catalyst demonstrates improved catalytic performance in the selective catalytic reduction of NOx by NH3 (NH3-SCR) as compared to the parent Fe-Beta. The catalyst exhibits 80–90% NOx conversion and 100% selectivity to N2 within wide temperature ranges: 180–500 °C (at GHSV = 18,000 h−1) and 260–500 °C (at GHSV = 54,000 h−1). Moreover, the dual-zone catalyst provides favorable NH3-slip removal efficiency even at NH3/NO = 1.60.
