Synthesis of Fe-Mn-Ce SCR Catalyst by Precipitation Method Using Different Precipitating Agents
Fe-Mn-Ce metal oxides nanosized particles have been prepared by co-precipitation approach using three kinds of precipitants NaOH, NH4OH and Na2CO3. The products were characterized by Powder X-ray Diffraction (XRD), Transmission Electron Microscopy (TEM) and BET study. It was found that the samples prepared with NH4OH as a precipitator show higher surface areas and larger sulfur capacity at low calcinations temperature. At high reaction temperatures, the samples prepared with Na2CO3 as precipitator exhibited much better activities for SCR of nitric oxide with ammonia than catalysts prepared with NH4OH and NaOH as the precipitants.
