This research aims to explore how WOx and VOx influence the NH3-SCR reaction pathway for NOx removal over MnOx/TiO2 catalysts.
Prepared MnOx/TiO2, WO3-MnOx/TiO2, and WO3-V2O5-MnOx/TiO2 catalysts using incipient-wetness impregnation.
Characterized catalysts to examine NO conversion, resistance to sulfur and water, and reaction mechanisms.
Conducted in situ DRIFTS analysis to identify mechanistic pathways of NH3-SCR.
WO3-V2O5-5MnOx/TiO2 catalyst achieved over 80% activity for NO conversion even after prolonged SO2 and H2O exposure.
The formation of W-O-Mn bonds regulated Mn valence, enhancing the catalytic reaction.
The combined L-H and E-R pathways were observed for WO3-5MnOx/TiO2 and WO3-V2O5-5MnOx/TiO2, differing from the L-H mechanism of 5MnOx/TiO2.
