MnOx-Based SCR Catalyst

Currently, W (or Mo)-modified V2O5/TiO2 catalyst has been industrialized for decades. However, vanadium oxide catalysts still have some defects, such as a narrow working temperature range (300–400 °C) and severe biological toxicity. Besides, SO2 and H2O could cause the deactivation of V-based catalysts, which also hinder their further application. For solving the mentioned problems, it is crucial to explore a highly-efficient and vanadium-free catalyst to replace V2O5-WO3(MoO3)/TiO2 for low-temperature NH3-SCR.
