“…Formation of the MnFe 2 O 4 structure favored the formation of oxygen vacancies, thereby improving catalyst stability and reactivity. 25,26 For the MF catalyst, two weak diffraction peaks were observed at 45.09°and 53.86°, which can be attributed to the formation of MnO 2 (PDF#42−1169) and Mn 3 O 4 (PDF#13−0162). Compared with the MF catalyst, the structure of the MFMo 4 catalyst did not exhibit any substantial change.…”

MnO x and MoO x , as additives, have proved effective in enhancing the NH 3 selective catalytic reduction activity of catalysts. In this study, a new Mn−Fe−Mo catalyst was prepared using both the precipitation method and impregnation method. The redox properties, surface acidity, and reaction intermediates of the prepared catalysts were analyzed using various techniques. The test results showed that the MFMo 4 catalyst achieved a NO x conversion rate exceeding 90% over the temperature range of 120−390 °C, demonstrating high potential to replace V-based catalysts due to outstanding activity at both high and low temperatures. The addition of MoO x exerted a detrimental impact on the redox property and avoided the production of N 2 O, thereby enhancing the N 2 selectivity. Furthermore, the codoping of MnO x and MoO x inhibited the adsorption of NO x on the catalysts while resulting in an increased number of Lewis acid sites on the catalyst. This promoted its reaction via the Eley−Rideal mechanism, which played a crucial role in ensuring the catalyst had excellent SCR activity over a wide temperature range.
