Abstract: V2O5-WO3(MoO3)/TiO2 catalysts are widely used in industrial denitrification (deNOx) processes based on the selective catalytic reduction (SCR) technique. To lower their cost and shorten the production cycle, V2O5-MoO3/TiO2 catalysts with and without CeO2 modification were prepared using the ball milling method. This study demonstrates that the CeO2-modified catalyst has high NO conversion and a broader temperature window due to the decreased amount of easily reducible vanadium species and the enhanced property of oxygen species activation in CeO2. Meanwhile, the SO2 resistance of the catalyst is restrained due to the strong adsorption and oxidation of SO2 over CeO2 in the catalyst.
