摘要

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 N₂ selectivity (>90%) at temperatures as low as 80–150 °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 large-scale manufacture of promising materials with superior deNO_x catalytic performances.
