Low temperature catalysts for selective catalytic reduction of NO_x with NH₃ plays an important role in flue gas treatments. Here, a two-dimensional MnFeCo layered double oxide were synthetized, characterized and employed as NH₃ selective catalytic reduction catalyst, showing excellent low temperature de-NO_x performance. MnFeCo layered double oxide exhibited a specific surface area of 92 m²/g with average pore size and volume of 2 nm and 1.5 cm³/g. At 100 °C, the MnFeCo layered double oxide performed an efficient NO conversion of 100 %. Even at 25 and 50 °C, NO conversions reached values of 49 and 86 %, respectively. Furthermore, the NO conversion reached an efficiency of 89 % in the presence of H₂O vapor (5 %) and SO₂ (100 ppm). Based on that, it can be said that this NH₃ selective catalytic reduction catalyst shows great potential in NO_x denitration of stationary industrial installations at a low temperature range.

用于用NH ₃选择性催化还原NO _x的低温催化剂在烟道气处理中起重要作用。在这里，二维MnFeCo层状双氧化物被synthetized，其特征在于并用作NH ₃选择性催化还原催化剂，表示脱NO优异的低温_X性能。MnFeCo层状双氧化物的比表面积为92 m ² / g，平均孔径和体积为2 nm和1.5 cm ³/G。在100°C下，MnFeCo层状双氧化物的有效NO转化率为100％。即使在25和50°C，NO转化率也分别达到49％和86％。另外，在H ₂ O蒸气（5％）和SO ₂（100ppm）的存在下，NO转化率达到89％。基于此，可以说该NH ₃选择性催化还原催化剂在固定的工业设备在低温范围内的NO _x脱硝中显示出很大的潜力。
