A series of Me-Fe/TiO2 catalysts was prepared via an aerosol-assisted deposition method, and used for the selective catalytic reduction of NO with NH3 (NH3-SCR) for the first time. Experimental results show that the spray-deposition Mn-Fe/TiO2, denoted Mn-Fe/TiO2(SD), demonstrates high NH3-SCR activity (> 95% conversion) with high N-2 selectivity (> 90%) at temperatures as low as 80-150 degrees C at a space velocity of 50,000 h(-1). Also, the benefits of the spray deposition for preparing Mn-Fe/TiO2 are highlighted by comparison with co precipitation and wet impregnation. This efficient and reliable technique offers attractive opportunities for largescale manufacture of promising materials with superior deNO catalytic performances.
