Synthesis of Cu0.5Mg1.5Mn0.5Al0.5Ox mixed oxide from layered double hydroxide precursor as highly efficient catalyst for low-temperature selective catalytic reduction of NOx with NH3

Abstract:

We report a novel NH3-SCR catalyst Cu0.5Mg1.5Mn0.5Al0.5Ox synthesized from layered double hydroxides with superior activity in a wide temperature range and improved SO2 and H2O resistance comparing to conventional doped Mn/γ-Al2O3. This catalyst results in a high NOx removal efficiency of 87.0–96.6% in the low temperature range of 100–250 °C, much better than Mn/γ-Al2O3 (35.0–67.2%). Besides, it exhibits significant resistance to SO2 and H2O due to the existence of Cu and Mg. The promoting ef...
