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.

通过气溶胶辅助沉积法制备了一系列Me-Fe / TiO ₂催化剂，并首次用于NH ₃（NH ₃ -SCR）选择性催化还原NO 。实验结果表明，喷涂沉积的Mn-Fe / TiO ₂表示为Mn-Fe / TiO ₂（SD），显示出高的NH ₃ -SCR活性（转化率> 95％）和高的N ₂选择性（> 90％）。在50,000 h ^-1的空速下，温度低至80–150°C 。另外，喷涂沉积对制备Mn-Fe / TiO ₂的好处通过与共沉淀和湿法浸渍比较来突出显示。对于具有超强DENO有前途的材料大规模生产这种高效和可靠的技术提供有吸引力的机会_X的催化性能。
