The Effect of Doping Ce and Fe on the Mn/TiO₂ Catalyst for Low Temperature NO Selective Catalytic Reduction with NH₃

Abstract:

A series of manganese-cerium oxide support titanium oxide with different Fe/Ti, Ce/Ti ratio were investigated for selectivity catalytic reduction of NO low at temperature with NH3 as a reducing agent. The catalysts base Mn/TiO₂ were prepared by sol-gel. The effect of amount of Ce and Fe oxide on the NO conversion of Mn/TiO₂2was studied. X-ray diffraction (XRD), temperature program desorption (TPD) were carried out. It was known that cerium oxides and iron oxide promoted preformance of Mn/TiO2 for low temperature. because Lewis is mainly take important role in the reaction for low temperature.
