In SCR, vanadium oxides act as catalysts to reduce NOx emissions from industrial flue gases. The process involves the reaction of NOx with ammonia (NH3) in the presence of V2O5, which facilitates the reduction of NOx to nitrogen (N2) and water (H2O). The high oxidation state of vanadium in V2O5 allows it to efficiently oxidize NO to NO2, which further reacts with NH3 to complete the reduction cycle.
