Abstract Niobium oxide, Nb2O5, remarkably enhanced the catalytic activity of FeOx for the reduction of NOx with NH3 and O2. Thus, for the reduction catalyzed by FeOx containing a small amount of Nb2O5, the conversion attained 90–100% in contrast to less than 40% for the reduction catalyzed by FeO without Nb2O5. The catalytic activity of the mixed oxide was scarcely affected by addition of SO2 to the reaction gas.
