The Effect of Ce Doping in FeTiOx Catalyst for the Selective Catalytic Reduction of NOx with NH3

The Ce doping in the environmentally-benign iron titanate (FeTiOx) catalyst could significantly enhance the low temperature activity for the selective catalytic reduction of NOx with NH3, which is important for its practical use especially for NOx removal from diesel engines in the cold-start process with low exhaust temperature.
